concurrency lock condition error when writing multiple records to an audit log table simultaneously.

  • Issue: Facing lock condition errors when writing multiple records to an audit log table simultaneously.
  • Setup:
    • One master pipeline invoking multiple child pipelines.
    • Audit log notebook placed in both master and child pipelines.
    • During a child pipeline failure, the notebook activity updates the audit log table in parallel for both child and master pipeline rows.
  • Problem: Despite updates being made as separate rows, lock conditions occur, causing pipeline errors.
  • Attempts to Resolve:
    • Applied partition by.
    • Used update statements.
    • These methods did not resolve the issue in Fabric.

Framed Question:

What are some effective strategies or best practices to avoid lock condition errors when writing multiple records to an audit log table simultaneously in a pipeline setup, especially in a Fabric environment?

Hi @SooryaP are you using the Warehouse service?  It uses snapshot isolation and has only table level locking. Concurrent UPDATE statements will likely cause issues. I explain further here:
