jvrao opened a new issue #1152: Add Stats to record Durability violations in write/read path.
URL: https://github.com/apache/bookkeeper/issues/1152
 
 
   
   **FEATURE REQUEST**
   
   1. Please describe the feature you are requesting.
   Durability contract demands that there are WQ copies spread across fault zones as per the ensemble placement policy. There are lots of areas where this contract is violated. Two areas that are well known are :
   a. During write path: if the write fails after satisfying AQ, that failure is dropped on the floor
   b. If the checksum error is detected on the read path, it is just ignored.
   This feature adds stats around both of these cases, so we can gauge the impact of durability violations in this path.
   
   2. Indicate the importance of this issue to you (blocker, must-have, should-have, nice-to-have). Are you currently using any workarounds to address this issue?
   
   Part of Durability work.
   
   3. Provide any additional detail on your proposed use case for this feature.
   
   Part of BP-31 which is waiting for merge.
   
   4. If there are some sub-tasks using -[] for each subtask and create a corresponding issue to map to the sub task:
