Subject: [PATCH 01/40] vtgate: add VEXPLAIN MYSQLPLAN statement

VEXPLAIN MYSQLPLAN <select> runs MySQL's EXPLAIN FORMAT=JSON against the
shards a SELECT would target, without executing the query itself. It
resolves each Route's target shards from its vindex at resolution time
and issues EXPLAIN against every resolved shard, attaching the per-shard
MySQL plan to the VTGate plan tree keyed by shard so per-shard plan and
cost differences are visible.

Unlike VEXPLAIN ALL, which executes the query to discover the shard-level
queries before explaining them, MYSQLPLAN never runs the wrapped query.

Only SELECT statements whose target shards can be resolved from a vindex
without reading cluster data are supported. DML (INSERT/UPDATE/DELETE),
and any query whose shard set depends on data - cross-shard joins,
subqueries, and lookup vindexes - are rejected at plan time with an error
pointing the user to VEXPLAIN ALL.

+
+A new `VEXPLAIN MYSQLPLAN <query>` statement runs MySQL's `EXPLAIN FORMAT=JSON` against the shards a `SELECT` would target, **without executing the query itself**. It resolves each `Route`'s target shards from its vindex at resolution time and issues `EXPLAIN` against every resolved shard, attaching the per-shard MySQL plan to the VTGate plan tree keyed by shard, so per-shard plan and cost differences are visible.

+Unlike `VEXPLAIN ALL`, which executes the query to discover the shard-level queries before explaining them, `VEXPLAIN MYSQLPLAN` never runs the wrapped query.

+Only `SELECT` statements whose target shards can be resolved from a vindex without reading cluster data are supported. DML (`INSERT`/`UPDATE`/`DELETE`), and any query whose shard set depends on data — cross-shard joins, subqueries, and lookup vindexes — are rejected with an error suggesting `VEXPLAIN ALL` instead.

Subject: [PATCH 02/40] vtgate: make VEXPLAIN MYSQLPLAN support check an
 allowlist

The support check for VEXPLAIN MYSQLPLAN was a denylist that rejected a
fixed set of primitive types and allowed everything else. Data-dependent
plans not on the list (e.g. recursive CTEs, whose Term-side Routes are
parameterized by rows produced at runtime) slipped through to a cryptic
"query arguments missing" error instead of the intended message pointing
the user at VEXPLAIN ALL.

Invert the check to an allowlist: permit a Route (with a resolvable
vindex) and the shard-independent container primitives that forward bind
variables to their inputs unchanged, keep the SELECT-only message for
DML, and default everything else to the "cannot resolve target shards"
rejection. This is fail-closed as new primitive types are added.

Add a recursive-CTE rejection case and a multi-Route (UNION) happy-path
test asserting each Route node carries its own per-shard EXPLAIN output.

Subject: [PATCH 04/40] vtgate: mirror no-route fallback in VEXPLAIN MYSQLPLAN

When a Route resolves to no shard but is marked for no-routes special
handling (e.g. an aggregate SELECT whose predicate maps to no shard),
normal execution falls back to an arbitrary shard so the query still
reaches a tablet. VEXPLAIN MYSQLPLAN now mirrors that fallback so it
produces EXPLAIN output for such a Route instead of attaching none.

Subject: [PATCH 06/40] vtgate: bind __upper_limit before EXPLAIN for
 pushed-down scatter limits

A bind-var scatter limit (e.g. `limit :limit, :offset`) plans as Limit ->
Route where the Route query uses `limit :__upper_limit`. VEXPLAIN MYSQLPLAN
recursed straight into the child Route with the original bind vars, so
`:__upper_limit` was never computed and EXPLAIN was sent with it unbound,
failing against a real tablet.

Mirror Limit.TryExecute: compute count+offset into a copied bind var map and
bind __upper_limit before recursing into the input.

Subject: [PATCH 07/40] vtgate: support explicitly targeted Send plans in
 VEXPLAIN MYSQLPLAN

A SELECT with an explicit shard/keyrange target plans as a bypass Send, not a
Route. That was rejected by the fail-closed allowlist even though the target
shards are trivially resolvable from the destination.

Accept a read Send in the allowlist (DML/DDL sends still reject) and, in the
explain walk, resolve its target destination and run EXPLAIN FORMAT=JSON per
shard, keyed by shard like Route. Factor the shared per-shard EXPLAIN loop into
explainOnShards.

 result conversion

VTGateProxy.VExplain dropped MySQLVExplainType into the default switch
branch and returned (nil, nil), silently discarding the JSON plan.
MYSQLPLAN uses the same single-column result shape as ALL, so convert it
via convertVExplainResultToString.

Subject: [PATCH 09/40] vtgate: reject VEXPLAIN MYSQLPLAN in
 reserved-connection sessions

Each EXPLAIN in MYSQLPLAN runs through ExecuteStandalone, which uses a
fresh autocommit session with no shard/reserved-connection state. When
the session holds a reserved connection (e.g. one that created a
temporary table), that separate connection cannot see the session-local
state, so the captured plan would not match the one the real query would
use - the SELECT works while its MYSQLPLAN fails or reports a misleading
plan.

Fail closed in that case with a dedicated UNIMPLEMENTED error. VEXPLAIN
ALL shares the same standalone-EXPLAIN path, so the message does not
point users at it.

Subject: [PATCH 10/40] vtgate: reject sequence next-value queries in VEXPLAIN
 MYSQLPLAN

A sequence next-value query plans as an unsharded Route with
Opcode == engine.Next and a nil vindex, so it passed the MYSQLPLAN
allowlist and MySQL was asked to EXPLAIN the Vitess-specific
'select next ... values' syntax it cannot parse. Reject it at plan
time with a dedicated error that does not point at VEXPLAIN ALL,
since ALL would execute the query and consume sequence values.

Subject: [PATCH 11/40] vtgate: bound VEXPLAIN MYSQLPLAN fanout and account for
 its shard queries

VEXPLAIN MYSQLPLAN previously ran its per-shard EXPLAIN FORMAT=JSON
queries serially and never counted them in ShardQueries, so a wide
scatter reported zero shard queries even though it fanned out to every
shard.

Run the per-shard EXPLAINs concurrently through an errgroup bounded by
maxParallelMySQLExplains (8) so a wide scatter or a multi-Route plan
cannot fan out an unbounded number of shard queries at once. Shard
resolution stays serial - it is cheap and a pushed-down Limit must
compute __upper_limit before its child Route is visited.

Add RecordShardsQueried to the engine.VCursor interface and call it once
per run with the number of shards queried. ExecuteStandalone (unlike the
normal shard path) does not increment ShardQueries, so MYSQLPLAN now
reports N shard queries for an N-shard scatter, consistent with how
VEXPLAIN ALL accounts for the same query.

Subject: [PATCH 12/40] vtgate: copy bind vars per input when collecting
 MYSQLPLAN tasks

collectMySQLExplainTasks passed the same bindVars map to every input of a
container primitive. A Route's findRoute mutates that map in place - a
DBA/information_schema route writes the resolved schema/table replacement
bind vars under fixed keys - and the collected task keeps the map pointer.
For a container with independent inputs (e.g. the arms of a Concatenate
built from a UNION), a later sibling's findRoute could overwrite an
earlier task's bindings before runMySQLExplainTasks executed, so VEXPLAIN
MYSQLPLAN over a UNION of routable information_schema SELECTs would EXPLAIN
the first route with the second arm's table binding.

Give each input its own copy in the recursion, mirroring how Concatenate
copies bind vars per source before executing each arm.

 For queries eligible for deferred plan optimization (where equal bind variable values let the plan collapse to a single shard at execution time), `VEXPLAIN MYSQLPLAN` explains the general (baseline) plan rather than the value-specific optimized one, so it reports the full shard footprint the query can target regardless of the bind variable values supplied.
 
+The per-shard `EXPLAIN` queries are run concurrently. If the `EXPLAIN` against any targeted shard fails (for example, an unreachable shard), the whole `VEXPLAIN MYSQLPLAN` command fails with that error rather than returning a partial result — matching the default all-or-nothing behavior of a scatter query.

primitiveToPlanDescriptionWithShardedSQLResults (MYSQLPLAN) and
primitiveToPlanDescriptionWithSQLResults (ALL) were near-verbatim copies
of the same recursive walk, differing only in the shape of the results
map and the one line attaching mysql_explain_json. Extract the shared
walk into primitiveToPlanDescriptionWith, which takes an attach closure
so each caller decorates nodes with its own EXPLAIN output. No behavior
change.

 MYSQLPLAN accounting

runMySQLExplainTasks recorded len(tasks) in ShardQueries up front, which
included tasks whose EXPLAIN returned no rows and were silently skipped.
Count only the shards that actually produced an EXPLAIN plan, incremented
under the existing mutex after the zero-row guard, and record the total
after the errgroup completes.

Subject: [PATCH 16/40] test/e2e: add unsharded keyspace for VEXPLAIN MYSQLPLAN
 reserved-conn test

TestVExplainMySQLPlanReservedConn creates a temporary table to pin the
session to a reserved connection, but the vexplain e2e cluster only had a
sharded keyspace, where Vitess rejects CREATE TEMPORARY TABLE (errno 1235).
The test therefore failed before it could exercise the MYSQLPLAN rejection.

Start an unsharded keyspace alongside the existing sharded one and target it
before creating the temp table, mirroring the vtgate/queries/dml suite.

Subject: [PATCH 17/40] vtgate: reject nested query blocks in VEXPLAIN
 MYSQLPLAN at plan time

Reject a wrapped SELECT containing a subquery, derived table, or common
table expression from the original AST before any shard RPC. Such a query
can merge into a single Route the primitive allowlist accepts, but EXPLAIN
FORMAT=JSON materializes a derived table during optimization - running any
stored function inside it once per shard - which would violate MYSQLPLAN's
promise never to execute the wrapped query.

Add a regression test asserting these shapes send no tablet queries.

Subject: [PATCH 18/40] vtgate: reject VEXPLAIN MYSQLPLAN sequence queries
 before bypass planning

A sequence next-value query was only rejected via the primitive allowlist
(Route.Opcode == Next). A session with an explicit shard/keyrange target
routes through bypass planning, which represents the query as a read Send
rather than a Route, so the allowlist accepted it and would have sent the
Vitess-specific 'select next ... values' syntax to MySQL as EXPLAIN.

Detect the sequence statement on the AST before planning so targeted and
untargeted sessions fail-fast the same way, before any tablet RPC, and drop
the now-unreachable Route.Opcode == Next branch from the allowlist.

Subject: [PATCH 19/40] vtgate: count completed shards when a MYSQLPLAN EXPLAIN
 fails

runMySQLExplainTasks discarded the accumulated shard count when any
per-shard EXPLAIN failed, returning before RecordShardsQueried. A wide
scatter where one shard errors after others succeed reported zero shard
queries in the query log and plan statistics even though tablet RPCs ran.

Record the count of completed EXPLAINs before propagating the error, so
the shards that did run are accounted for. errgroup.Wait blocks until all
tasks finish, so the count is final at that point. This keeps the existing
"count only successfully-explained shards" semantic and matches how the
normal shard path records attempted shards regardless of shard-level errors.

Subject: [PATCH 20/40] vtgate: count every attempted shard in MYSQLPLAN
 accounting

runMySQLExplainTasks only counted shards whose EXPLAIN returned a nonempty
plan, so ShardQueries and accumulated plan statistics under-reported shards
whose EXPLAIN errored or returned no rows. This diverged from
VCursorImpl.ExecuteMultiShard, which counts the targeted shards up front
regardless of per-shard outcome.

Record one shard query per task before running them, matching the normal
shard path. This reverses the earlier "count only successfully-explained
shards" behavior; the empty-result and error accounting tests now expect the
full attempted count.

Subject: [PATCH 21/40] vtgate: reject VEXPLAIN MYSQLPLAN advisory lock
 functions

A SELECT of an advisory lock function (get_lock, release_lock,
release_all_locks, is_free_lock, is_used_lock) plans as an engine.Lock
primitive, which is neither in the MYSQLPLAN allowlist nor the DML list, so
it fell through to the default rejection that points the user at VEXPLAIN
ALL. Following that advice runs the wrapped SELECT, which executes the lock
function and acquires or releases advisory locks as a side effect.

Detect the lock function on the AST before planning, like the sequence case,
and reject it without pointing at VEXPLAIN ALL. The read-only is_free_lock
and is_used_lock are rejected uniformly: they are equally unexplainable
through MYSQLPLAN.

Subject: [PATCH 22/40] vtgate: don't pin a VEXPLAIN MYSQLPLAN session for a
 SET_VAR-only sysvar

CheckForReservedConnection treated a VExplainStmt as an unknown statement
and fell through to NeedsReservedConn, so planning VEXPLAIN MYSQLPLAN in a
session that had only set a SET_VAR-eligible sysvar (e.g. sql_mode) pinned
the session and tripped the MYSQLPLAN reserved-connection guard with a
misleading temporary-table error. Unwrap the VExplainStmt and decide against
its inner statement, so a VEXPLAIN of a SELECT is treated like the SELECT and
is not spuriously pinned. The SET_VAR hint rides on the inner SELECT, so the
standalone EXPLAIN still honours the sysvar.

Subject: [PATCH 23/40] vtgate: reject VEXPLAIN MYSQLPLAN of
 SQL_CALC_FOUND_ROWS with GROUP BY/HAVING

The nested-query guard walks the original AST, where SELECT SQL_CALC_FOUND_ROWS
has no derived table. But when a LIMIT and GROUP BY/HAVING are present, the
planner rewrites the row-count half into `select count(*) from (select ...) as t`
(buildSQLCalcFoundRowsPlan), wrapping the original SELECT in a derived table.
Because SQLCalcFoundRows is on the MYSQLPLAN primitive allowlist, that query
would ship to every shard inside EXPLAIN FORMAT=JSON, which can materialize the
derived table during optimization and run a stored function once per shard -
violating MYSQLPLAN's promise never to run the wrapped query.

Add an AST guard that rejects exactly this shape before planning, with a
dedicated message pointing at VEXPLAIN ALL. The condition matches the planner's
rewrite trigger precisely: without a LIMIT the directive is ignored, and without
GROUP BY/HAVING the count query reuses the original SELECT with a single
count(*), so neither introduces a derived table.

Subject: [PATCH 24/40] docs: note VEXPLAIN MYSQLPLAN does not table-ACL-check
 per-shard EXPLAINs

EXPLAIN statements carry no table permissions (BuildPermissions routes them to
the no-op case), so vttablet never runs a table-ACL check on the explained
tables. This hole predates VEXPLAIN MYSQLPLAN - a plain EXPLAIN through vtgate
already reaches one arbitrary shard unchecked - but MYSQLPLAN widens it to every
resolved shard of every keyspace in the plan, and unlike VEXPLAIN ALL nothing
ACL-checked ever runs. Query denylist rules still apply.

Closing the hole correctly (deriving the wrapped statement's permissions) is a
compatibility-sensitive behavior change to a shared tabletserver path and
belongs in its own PR. For now, document the limitation in the 25.0 summary and
add a characterization test pinning that EXPLAIN yields no permissions, using
the exact per-shard query shape MYSQLPLAN issues, so a future deep fix must
update it consciously.

Subject: [PATCH 25/40] vtgate: give VEXPLAIN MYSQLPLAN derived-table/view
 rejection an honest message

The nested-query guard rejected derived tables and views with the generic
"cannot resolve the target shards (cross-shard join, subquery, or lookup
vindex)" message, which names none of the actual reasons an otherwise-routable
derived table or view is refused. Split the *sqlparser.DerivedTable case out
into its own message that names derived tables and views and explains the
materialization hazard; subqueries and CTEs keep the generic message.

Subject: [PATCH 26/40] vtgate: make MYSQLPLAN shard-query accounting an
 optional VCursor capability

RecordShardsQueried was added directly to the exported engine.VCursor
interface, which breaks any out-of-tree VCursor implementation at compile
time. Move it to a separate single-method ShardsQueriedRecorder interface and
type-assert to it at the VEXPLAIN MYSQLPLAN call site, so a VCursor that does
not track shard-query stats simply skips the accounting instead of failing to
compile. VCursorImpl satisfies the optional interface implicitly, so accounting
is unchanged.

Subject: [PATCH 27/40] vtgate: run VEXPLAIN MYSQLPLAN EXPLAINs through the
 shared scatter path

VEXPLAIN MYSQLPLAN previously fanned its per-shard EXPLAIN FORMAT=JSON
queries out with its own errgroup, bounded by maxParallelMySQLExplains,
issuing each shard's EXPLAIN through ExecuteStandalone. That duplicated
the scatter machinery, capped concurrency differently from a real
scatter, and relied on an optional ShardsQueriedRecorder to account for
the shard queries because ExecuteStandalone does not increment
ShardQueries on its own.

Extract the shared fan-out from ScatterConn.ExecuteMultiShard into a
private executeMultiShard helper that runs one query per shard and hands
each shard's result to a collect callback (serialized under the existing
mutex). ExecuteMultiShard keeps merging via AppendResult; a new
ExecuteMultiShardPerShard keeps the per-shard results aligned by index so
callers can attribute each to its shard. Expose it through the Executor,
the iExecute interface and VCursorImpl, where it runs in a fresh
autocommit session and never requests FetchLastInsertId - so, unlike
ExecuteMultiShard, it never writes SafeSession.LastInsertId and cannot
race on it.

MYSQLPLAN now type-asserts the VCursor to a new optional
MultiShardPerShardExecutor interface and issues one
ExecuteMultiShardPerShard call per Route/Send, reusing the normal
scatter's retry, transaction and accounting behavior: every targeted
shard is counted in ShardQueries and a failure against any shard fails
the whole command. This removes maxParallelMySQLExplains, the bespoke
errgroup fan-out and the now-dead ShardsQueriedRecorder /
RecordShardsQueried plumbing.

 MYSQLPLAN allowlist

engine.MergeSort is only ever constructed at stream-execute time (in
route.mergeSort), never emitted by the planbuilder into a compiled plan
tree, so the *engine.MergeSort case in checkVExplainMySQLSupported could
never match. Remove it; the fail-closed default reject already covers the
impossible case correctly. No behavior change.

Subject: [PATCH 29/40] test/e2e: probe MySQL version from the sharded keyspace
 by name

TestVExplainMySQLPlan gates its query_block assertion on the MySQL flavor of
clusterInstance.Keyspaces[0], but since the unsharded keyspace was added it
starts first, so Keyspaces[0] is the unsharded keyspace, not the sharded one
the MYSQLPLAN query runs against. Positional indexing into Keyspaces is fragile
because the slice order follows keyspace startup order in TestMain.

Add a keyspaceByName helper and look the sharded keyspace up by name for the
version probe. Route the reserved-connection test's unsharded-keyspace usage
through the same helper so keyspace lookups are consistent.

Subject: [PATCH 30/40] test/e2e: cover VEXPLAIN MYSQLPLAN scatter fan-out
 across shards

Every existing MYSQLPLAN e2e assertion used a single-shard point query, so the
per-shard EXPLAIN fan-out that the multi-shard executor performs was only
covered by unit tests. Add a scatter SELECT (no WHERE) to TestVExplainMySQLPlan
and assert the result carries per-shard EXPLAIN output keyed by at least two
distinct shard names, proving the fan-out end-to-end against real MySQL.

Subject: [PATCH 31/40] vtgate: rename MYSQLPLAN output key to
 mysql_explain_json_by_shard

VEXPLAIN MYSQLPLAN attaches a per-shard map (shard name -> MySQL EXPLAIN
FORMAT=JSON output) to each Route/Send node, whereas VEXPLAIN ALL attaches a
single EXPLAIN blob. Both used the same "mysql_explain_json" key, which
misrepresents the MYSQLPLAN value as a single plan rather than a by-shard map.

Rename only the MYSQLPLAN key to "mysql_explain_json_by_shard" so its shape is
self-describing; VEXPLAIN ALL keeps "mysql_explain_json". MYSQLPLAN is new and
unreleased in v25, so there is no compatibility concern with the rename.

Subject: [PATCH 32/40] vtgate: fold VEXPLAIN MYSQLPLAN AST checks into one
 walk

The nested-query, sequence, and advisory-lock rejections each ran their own
sqlparser.Walk over the statement. Combine them into a single checkVExplainMySQLAST
walk with one type switch that aborts on the first offending node, and merge their
rationale into one doc comment. No behavior change for single-violation queries;
the SQL_CALC_FOUND_ROWS check stays separate as it is a top-level type assertion,
not a walk.

Subject: [PATCH 33/40] vtgate: reject VEXPLAIN MYSQLPLAN DML by statement type

checkVExplainMySQLSupported hand-listed eight DML engine primitives (Insert,
InsertSelect, Upsert, Update, Delete, DMLWithInput, FkCascade, FkVerify) just to
give DML a SELECT-only error message; that list would drift as new DML primitives
are added. Reject DML up front with sqlparser.IsDMLStatement before planning
instead, and drop the engine-primitive case. The fail-closed default still catches
anything unexpected; the DML/DDL bypass-Send guard stays as it keys off stable
flags, not a type list.

Subject: [PATCH 35/40] vtgate: warn when a MYSQLPLAN shard returns an empty
 EXPLAIN result

EXPLAIN FORMAT=JSON always returns one row of one column, and a per-shard failure
already aborts the whole command, so an empty result in runMySQLExplainTasks is
anomalous. Previously that shard was dropped from the output map silently; now we
log a warning with the keyspace and shard before omitting it. Adds a test that
captures log.Warn to prove the warning fires and the shard is omitted.

rather than uncommitted changes - the same limitation as VEXPLAIN ALL. Document it
alongside the other MYSQLPLAN runtime caveats.

Subject: [PATCH 37/40] test/e2e: assert VEXPLAIN MYSQLPLAN of INTO
 OUTFILE/DUMPFILE has no side effect

VEXPLAIN MYSQLPLAN wraps the target query in EXPLAIN FORMAT=JSON, which
never executes it, so a SELECT ... INTO OUTFILE/DUMPFILE reaching a shard
writes no file. Add an end-to-end test on the unsharded keyspace that reads
the tablet's secure_file_priv directory, confirms a real SELECT ... INTO
OUTFILE writes there (proving the path works), then asserts that
VEXPLAIN MYSQLPLAN of the OUTFILE and DUMPFILE variants returns a plan and
writes no file.

Subject: [PATCH 38/40] changelog: clarify VEXPLAIN MYSQLPLAN concurrency is
 per-shard, not per-route

The release note said the per-shard EXPLAIN queries run concurrently without
qualification, which implied a multi-Route plan (e.g. a UNION) explains every
route at once. In fact each Route fans out EXPLAIN FORMAT=JSON across its shards
concurrently, but plans with multiple Route nodes explain each route in turn.
Reword the note to reflect the shard-level (not route-level) concurrency.

Subject: [PATCH 39/40] vtgate: give lock/sequence rejection priority in
 VEXPLAIN MYSQLPLAN AST walk

checkVExplainMySQLAST recorded each offending node into a shared astErr and
returned (false, nil), but sqlparser.Walk treats false as pruning only the
current node's children, not aborting the walk. So astErr held the last offender
visited, and offending nodes hid their children. For a query like
'select get_lock(...), (select 1)' the sibling subquery overwrote the lock
rejection with the generic 'use VEXPLAIN ALL instead' message; for
'select (select get_lock(...))' the outer subquery pruned the inner lock
function entirely. Either way the user was steered to VEXPLAIN ALL, which would
execute the query and acquire the advisory lock - the side effect the lock
rejection exists to prevent.

Give the lock and sequence rejections (which must never recommend VEXPLAIN ALL)
priority: return their error from the visitor to abort the walk immediately, and
have the derived-table/subquery cases record only the first match while
continuing to descend, so a lock or sequence node anywhere in the tree still
overrides the recommend-ALL message. Add unit tests for the sibling and nested
cases.

Subject: [PATCH 40/40] changelog: note table-scoped query denylist rules also
 bypass MYSQLPLAN EXPLAINs

The summary claimed outright that query denylist rules still apply to the
per-shard EXPLAIN queries VEXPLAIN MYSQLPLAN issues. That is only true for rules
conditioned on the query pattern; rules conditioned on a table name are not
enforced, for the same reason the per-shard EXPLAINs skip table ACL checks - the
tablet plans an EXPLAIN as PlanSelect without the explained table's identity, so
tableMatch never matches a table-scoped rule. Correct the note to spell this out
and extend the operator guidance to cover table-scoped denylist rules.
