integrate cost model better with datafusion+optd #195

skyzh · 2024-10-27T19:27:14Z

persist statistics somewhere inside the execution engine (i.e., persist base table statistics in datafusion catalog?)
implement analyze command + executor to compute base table statistics

part of https://github.com/cmu-db/optd/issues/195 * also refactors the adv-cost crate to purely support cardinality estimation * rewrite optimize input task to reduce dead code (which might have some effect on the plan output?) * use `cargo run -p optd-sqlplannertest --bin planner_test_apply -- --enable-advanced-cost-model` to experiment with the advanced cost model --------- Signed-off-by: Alex Chi <[email protected]>
