Polecat side of the per-database rebuild concurrency cap train (jasperfx#420 / jasperfx#463, epic jasperfx#486 WS3) — the companion jasperfx#434's list called for. Marten twin: JasperFx/marten#4878.

IEventStore.MaxConcurrentRebuildsPerDatabaseoverride onDocumentStore, read by theprojections rebuildCLI fan-out: explicitStoreOptions.DaemonSettings.MaxConcurrentRebuildsPerDatabasewins (zero/negative opts back into unbounded), else a derivedmax(1, MaxPoolSize / 8)from the SqlClient connection pool, else null (historical unbounded).TryCreateUsagepopulatesEventStoreUsage.MaxConcurrentRebuildsPerDatabaseso CritterWatch#309's rebuild dispatcher can size its orchestration off the wire.Tests
rebuild_concurrency_cap_resolution(5, connection-free): configured knob wins; non-positive disables; pool 64 → 8; pool 5 → floors at 1; descriptor carries the effective cap.🤖 Generated with Claude Code
