#3450 feat(targets): Use the presence of `_sdc_deleted_at` to flag records for deletion in hard-delete mode Pull request opened by edgarrmondragon on <!date^1768422999^{date_short}|2026-01-14T20:36:39Z> Related • Closes #3444 Summary by Sourcery Implement hard-delete handling for log-based replication using the

_sdc_deleted_at

flag and expose a key-based delete API for SQL connectors. New Features: • Add support in SQL sinks for hard deleting records marked with

_sdc_deleted_at

during LOG_BASED replication when

hard_delete

is enabled. • Introduce a connector-level

delete_by_key

method to delete rows by primary key across SQL targets. Enhancements: • Preserve

_sdc_deleted_at

metadata on records when

hard_delete

is enabled so it can be used to drive hard deletes. Tests: • Add SQLite target tests covering hard delete and soft delete behavior for log-based replication, including composite primary key scenarios. meltano/sdk
