#3453 refactor: Insert then delete Pull request opened by edgarrmondragon on <!date^1768505009^{date_short}|2026-01-15T19:23:29Z> • On top of #3450 Summary by Sourcery Refactor SQL hard-delete handling to upsert then delete based on the soft delete column for LOG_BASED replication. New Features: • Introduce a generic bulk_upsert_records method on SQLSink for database-specific bulk upsert implementations using the table schema. Bug Fixes: • Ensure hard delete processing works even when records already exist by upserting before deleting rows marked as deleted. Enhancements: • Simplify SQLSink hard delete flow by removing record-splitting logic and delegating deletion to a connector-level method using the soft delete column. • Replace key-based deletion with a connector method that deletes all rows where the soft delete column is set, improving consistency and reducing required inputs. meltano/sdk
