V9.6.0

There's a couple tenant aware APIs that are new, so this had to be a minor point bump. The majority of the work in this release was stress testing projection rebuilds and ensuring there was never any concurrent access of un-thread safe dictionaries inside of the async daemon that happened as a side effect of 9.0 changes.

What's Changed

• Bump version from 9.5.2 to 9.5.3 by @erdtsieck in #4662
• Bump Weasel.Postgresql + Weasel.EntityFrameworkCore 9.0.2 → 9.0.3 by @jeremydmiller in #4664
• #4667 Phase 1 — write-path *Projected variants bypass session-shared trackers by @jeremydmiller in #4669
• #4667 Phase 2 — read-path LoadProjectedAsync bypasses session-shared trackers by @jeremydmiller in #4670
• #4667 Phase 3 — ProjectionDocumentSession routes user-code LoadAsync through projection-safe path by @jeremydmiller in #4671
• #4666 Phase A — Marten.ScaleTesting CLI + event seeder by @jeremydmiller in #4672
• #4668 — tenant-aware RebuildSingleStreamAsync overloads on AdvancedOperations by @jeremydmiller in #4674
• #4665 — bump JasperFx 2.8.0 → 2.8.2 + CatchUpAsync per-tenant repro test by @jeremydmiller in #4673
• #4666 Phase B — TelehealthComposite 4+2+2 + rebuild subcommand by @jeremydmiller in #4675
• #4666 Phase C — validate + stress subcommands by @jeremydmiller in #4676

Full Changelog: V9.5.3...V9.6.0

V9.5.3

This is a little optimization to the new 9.* code that eliminated the runtime codegen, and a fix for the daemon being a little vulnerable to concurrency in its internals -- which is also an optimization here.

What's Changed

• Fix #4657: bypass session VersionTracker from projection StoreProjection (async daemon race) by @jeremydmiller in #4658
• #4659 Phase 1 — eliminate ConcurrencyMode runtime branches via type splits in closed-shape by @jeremydmiller in #4660
• #4659 Phase 2 — hierarchy selector split eliminates last per-row branch by @jeremydmiller in #4661

Full Changelog: 9.5.2...V9.5.3

9.5.2

Bug fixes

• #4619 (#4632) — mt_archive_stream emits explicit column lists in its INSERT…SELECT, surviving ALTER TABLE ADD COLUMN migrations that reorder the physical column layout (previously failed with 42804 after a column was added to mt_events).
• #4625 (#4633) — BulkInsertEventsAsync writes mt_streams.type from the StreamAction's AggregateType, restoring UseMandatoryStreamTypeDeclaration support on the bulk path.
• #4641 (#4646) — AddMartenManagedTenantsAsync no longer leaves a half-installed schema under AutoCreate.None. The admin call eagerly applies the events feature via a per-feature CreateMigrationAsync + scoped CreateOrUpdate apply, so the next append succeeds end-to-end on a virgin schema (previously failed with 42P01 / 42883).
• #4645 (#4647) — DCB non-HStore tag query JOIN now includes e.tenant_id = t.tenant_id, eliminating own-event duplication under per-tenant sequences with UseTenantPartitionedEvents.

Test coverage

• #4617 closed — full TenantPartitionedEventsTests project (~170 tests across 50 files) covering append / read / projections / admin / DCB / async daemon / regressions under UseTenantPartitionedEvents.
• Three projection coverage gaps closed: #4650 (FlatTableProjection), #4651 (DetermineActionAsync), #4652 (doc-tables-NOT-partitioned-by-default invariant).
• #4649 investigated and pinned as documented intentional asymmetry — AutoCreate.CreateOnly continues to work via the lazy schema-apply path, by design (no SUT change needed).

Known follow-up — NOT in this release

• #4648 — AddGlobalProjection × UseTenantPartitionedEvents fails MT002 because the global event decorator writes to the *DEFAULT* tenant slot, which can't be a Postgres partition suffix. Test pin is in master asserting the throw; the underlying fix requires either routing global-aggregate events through a sibling non-partitioned table or reserving a default-tenant partition suffix. Marked as an enhancement, deferred to a later release.

V9.4.0

Marten 9.4.0

Per-tenant event partitioning and a tenant-aware async projection daemon (#4596 / CritterWatch#209). Built on JasperFx 2.5.0.

Highlights

• Per-tenant event partitioning — opt in with opts.Events.UseTenantPartitionedEvents = true. On top of conjoined event tenancy, Marten partitions mt_events / mt_streams by tenant_id (native PostgreSQL LIST partitioning), gives each tenant its own event sequence (mt_events_sequence_{suffix}), and keys mt_event_progression by (name, tenant_id). Removes the single shared event store as a scalability bottleneck across tenants.
• Tenant-aware async daemon — vectorized per-tenant high-water detection (one query per database reports the high-water position for every active tenant), per-tenant projection rebuild isolation, and cross-tenant rebuild fan-out.
• Composite single-pass rebuild executor — read-once / fan-out rebuild for composite projections, with progression keyed on the composite's single {Name}:All shard.

Constraints for per-tenant partitioning

Validated at DocumentStore construction:

• Requires Events.TenancyStyle = TenancyStyle.Conjoined.
• Requires a quick append mode (EventAppendMode.Quick / QuickWithServerTimestamps); EventAppendMode.Rich is out of scope.
• Cannot currently be combined with Events.UseArchivedStreamPartitioning (sub-partitioning by both tenant_id and is_archived is a planned follow-up).

The flag defaults to false; existing stores keep the global append path byte-for-byte.

Dependencies

• Consumes the released JasperFx 2.5.0 packages (per-tenant partitioning surface, tenant-aware daemon abstractions, composite rebuild executor, and the SubscriptionAgent optimized-rebuild double-load fix).

Documentation

• New Per-Tenant Event Partitioning guide, cross-linked from Optimizing for Performance and Scalability.
