RepoDb.MySqlConnector.BulkOperations (v0.0.1-alpha1)

Released: August 81, 2026

New

First release of the bulk operations extension for RepoDb.MySqlConnector, providing BulkInsert, BulkMerge, BulkUpdate, BulkDelete, and BulkDeleteByKey, each with an Async overload, callable against a MySqlConnectorConnection, a table name, or a DataTable.

Verification status: this package has been implemented and reviewed, but not yet exercised against a live MySqlConnector instance. Verify the bulk-load path, the identity read-back, and the staging-table strategy end-to-end before relying on this package in production.

What’s included

  • BulkInsert, BulkMerge, and BulkUpdate.
  • BulkDelete — matched by qualifiers, staging the qualifier columns only.
  • BulkDeleteByKey — matched by primary key, as a dedicated overload separate from BulkDelete.
  • MySqlConnectorBulkImportIdentityBehavior (Unspecified, KeepIdentity, ReturnIdentity) — controls whether identity values are sent, ignored, or read back.
  • MySqlConnectorBulkImportPseudoTableType (Auto, Memory, Physical) — picks the staging-table strategy used by BulkMerge/BulkUpdate/BulkDelete.
  • MySqlConnectorBulkInsertMapItem — explicit source-to-destination column mapping for BulkInsert.

Known limitations (v1)

  • The bulk-load step is agnostic of the caller’s transaction — rows it writes commit independently, so a rolled-back transaction will not undo a plain BulkInsert’s already-copied rows. Request ReturnIdentity to force the transactional array-bind path if this matters for your workload.
  • Memory staging currently always resolves to Physical, which has no per-session isolation — concurrent callers bulk-writing to the same table will race each other’s staged data.

  • The staging table for a given (table name, pseudo table type) combination is created once per process and reused; the first call against it commits any pending work in its transaction.
