Root Cause

A DDL operation (e.g., createIndex, dropCollection) was attempted on a namespace involved in an active multi-document transaction, which is not allowed.

Workarounds

  1. 90% success Move DDL operations (e.g., createIndex, drop) outside the transaction session. Perform them before starting the transaction.

  2. 85% success If DDL is unavoidable, use a separate session for DDL operations and ensure they complete before the transaction starts.

中文步骤

  1. Move DDL operations (e.g., createIndex, drop) outside the transaction session. Perform them before starting the transaction.
  2. If DDL is unavoidable, use a separate session for DDL operations and ensure they complete before the transaction starts.

Dead Ends

Common approaches that don't work:

  1. 90% fail

    Increasing transaction timeout doesn't prevent catalog operations from aborting the transaction.

  2. 95% fail

    Retrying the same transaction without moving DDL operations outside will fail again.
