…paths The documented sync-layer schema creates corsair_entities and corsair_accounts with no secondary indexes, yet every ORM read filters corsair_entities on (account_id, entity_type[, entity_id]) and resolves the account by (tenant_id, integration_id) before every entity op. With no matching index these are full table scans whose cost grows with the total row count across all tenants and plugins — on the very table the sync layer writes to on every webhook event. Add plain (non-unique) covering indexes to every hand-authored schema (docs + demos). A non-unique index delivers the full lookup speedup without changing any runtime failure mode. Enforcing UNIQUE on (account_id, entity_type, entity_id) is deferred to the follow-up that makes upsertByEntityId atomic (ON CONFLICT DO UPDATE): only paired with conflict handling does the constraint avoid turning a concurrent first-insert race into a failed operation, and it avoids a migration hazard on existing databases that already hold duplicate rows. Benchmark (sqlite, documented schema, findByEntityId pattern): 900k rows 61ms -> 9us per lookup; EXPLAIN QUERY PLAN goes from SCAN corsair_entities to SEARCH USING INDEX.

Update the Quick Start schema to include both indexes.
docs/quick-start.mdx Lines 92-113 still create corsair_accounts and corsair_entities without the new indexes. Users who follow the linked setup do not receive these indexes, so the common setup path still performs full-table scans. Add the same indexes to docs/quick-start.mdx before merge.

perf(db): index corsair_entities and corsair_accounts on their query paths
Related to #1027
Description
The documented sync-layer schema creates
corsair_entitiesandcorsair_accountswith no secondary indexes, yet the ORM always filters on non-PK columns:packages/corsair/db/kysely/orm.tsbaseQuery→WHERE account_id = ? AND entity_type = ?(+entity_idon thefindByEntityId/upsertByEntityIdpaths).packages/corsair/core/account-lookup.ts:48-51→WHERE tenant_id = ? AND integration_id = ?, run before every entity operation to resolve the account.With no matching index these are full table scans that grow with total rows across all tenants and plugins — on the table the sync layer writes on every webhook event.
This adds plain (non-unique) composite indexes on the lookup columns:
docs/concepts/database.mdxdocs/quick-start.mdxdocs/guides/dashboard.mdxdemo/testing/migration.sqldemo/testing/src/db/schema.ts+drizzle/0001_entities_account_index.sqldemo/mcp/db.tsUNIQUEIf the tables already exist, run only the two
CREATE INDEXstatements.Non-unique, by design
An earlier revision made the entities index
UNIQUE (account_id, entity_type, entity_id). Both automated reviewers correctly flagged that this couples a correctness invariant into a perf change, with two side effects:upsertByEntityIdis a non-atomic lookup-then-insert, two concurrent first-time upserts for the same entity would both miss the SELECT; the unique index then rejects the second INSERT and the operation fails instead of upserting.The perf goal (issue #1027) only needs an index for the equality lookup — the benchmark speedup is identical with a non-unique index, and it changes no runtime failure mode and creates no migration hazard. Enforcing
UNIQUEbelongs with the follow-up that makesupsertByEntityIdatomic (ON CONFLICT DO UPDATE, cf. #619): only paired with conflict handling does the constraint make sense. So this PR ships the plain index; the unique constraint + atomic upsert is a separate PR.Benchmark
