WalkthroughBulk mode adds monthly, quarterly, and yearly batching, JDBC-backed progress state, bulk pipeline dispatch, bulk date propagation, and transformer-managed output writes. It also adds configuration, notifications, database migration, and integration coverage. ChangesBulk processing and state management
Estimated code review effort: 4 (Complex) | ~60 minutes Merge Risk: 🟠 High · up to The bulk mode changes scheduling and persisted completion tracking; the current implementation can skip intermediate processing, omit required date information, and silently accept missing state updates, while interruptions can replay transformer-managed writes. These issues can produce incomplete or duplicated historical output, so the PR is not merge-ready until the bulk scheduling and state transitions are corrected. Sequence Diagram(s)sequenceDiagram

The five-second timeout adjustment in ThreadUtilsSuite and the kafka-clients spelling correction in Versions.scala are unrelated to bulk processing or transformer-controlled writes.

Resume nonterminal bulk phases.
Line 196 treats Processed, Repartition1, and Repartition2 as completed. These phases are not Done. After an interruption in one of these phases, the scheduler creates a Skip("already processed") task and cannot run the required repartition continuation.
Skip only Done. Map each nonterminal phase to its required continuation task.

Persist the info-date column in BulkLoadState.
Line 201 stores "" for the info-date-column field. The persisted state then has no column identifier for the required output-table repartitioning. Pass the actual output info-date column when creating the state.
