> if updateDetails for updating task status gets failed to update or insert in RECON_TASK_STATUS table, then should we atleast update the relevant sync metric for success and failure ? Thanks @devmadhuu for the review. The OM sync success and failure metrics (`OzoneManagerSyncMetrics`, `ReconSyncMetrics`, `ReconTaskMetrics`) are in-memory counters updated by the sync code itself, not read from `RECON_TASK_STATUS`, so they stay correct when the status write fails. This patch makes them more accurate. Before, a failed status write after a successful delta sync was counted as a delta failure and triggered a full snapshot request. What can be out of date after a failed write is the `RECON_TASK_STATUS` row itself, which `ReconTaskStatusMetrics` and the task status API read, until the next successful write for that task. > May be you want to do in follow up PR or in this ? Yes, a counter for task status write failures would make that visible. Since it needs a metrics source wired into `ReconTaskStatusUpdater`, I filed HDDS-17512 as a follow-up. -- This is an automated message from the Apache Git Service.
