Impact

Transactions were NOT committed despite the explicit options.WithCommit flag using table service client. Because of this, clients did not commit changes to the transaction, relying on the fact that the transaction commit was successful. This led (in rare cases) to a loss of data consistency.

Patches

ydb-go-sdk contains this problem in versions from v3.104.6 to v3.134.1. The fix for this problem has been released in version v3.134.2 (https://github.com/ydb-platform/ydb-go-sdk/pull/2091).

Workarounds

Use explicit table.Transaction.CommitTx(ctx) instead use options.WithCommit().
Use transaction retrier db.Table().DoTx(ctx, lambda) instead explicit start transaction on session.
Use query client db.Query().Do(ctx, lambda) with the same logic in lambda
