JRASERVER-71759 - Getting issue details... STATUS

In Jira 8.10.0 we added versioning of Jira entities: issues, comments, worklogs.

From now every index operation replayed by other nodes contains also the version of entity which is requested to be re-indexed by other nodes.

It is possible that comments/worklogs re-index request may be added without version (i.e. version = 0).

8.10.X 8.11.X 8.12.X 8.13.0 8.13.1    

In Jira 8.10.x, 8.11.x, 8.12.x, 8.13.0, 8.13.1 every time a node re-indexes such entity the following warning is logged:

WARN [INDEX-REPLAY] Unexpected un-versioned operation added for processing: ReplicatedIndexOperation {indexTime=2020-09-18 09:01:34.136, id=3813938, nodeId='node1', affectedIdToVersion={85040=0, 90614=0, 86326=0, 85894=0, 90377=0, 85258=0}, operation=UPDATE, affectedIndex=COMMENT, entityType=NONE, backupFilename=''}

This does not cause any Jira index corruption. Such an entity is unconditionally re-indexed (vs versioned entities which are re-index only if the local index does not contain an entity with version greater or equal).  This message may be logged very frequently thus affect the Jira instance: frequent log file rotation, logging performance affected. 

There are a few scenarios where such a situation happens in a valid flow and should not cause any concern:

• after upgrading, when there is any action which triggers a full issue re-index (issue & comments & worklogs) the comments & worklogs which were created/updated in a version of Jira not supporting versioning, those comments&worklogs will have version 0
• when adding a comment which triggers a full issue re-index (before this comment is indexed & versioned), this new comment is first replicated with version = 0 (because of the full issue re-index) and then replicated with version 1
  
  

8.14.0 8.13.2 

Because of this we have slightly changed this log message in Jira >=8.14.0 and 8.13.2.

There is still a warning when processing an un-versioned issue entity. It should only happen just after ZDU (when a node may still process an index operation created by a node with no versioning). In any case this requires investigation:

WARN [INDEX-REPLAY] Unexpected un-versioned operation added for processing: ReplicatedIndexOperation {indexTime=... affectedIndex=ISSUE...}

When processing unversioned comments & worklogs entities, the log level and message changed to:

DEBUG [INDEX-REPLAY] Un-versioned COMMENT/WORKLOG operation added for processing: ReplicatedIndexOperation {indexTime=... affectedIndex=COMMENT...}

Note that there is still the aggregated (every 5 min) log [INDEX-REPLAY] which contains the number of un-versioned entities:

[INDEX-REPLAY] [STATS] Node replay index operations stats (total): ... compactUnVersionedCounter


[INDEX-REPLAY] [STATS] Node replay index operations stats (snapshot): ... compactUnVersionedCounter

Compare compactUnVersionedCounter vs compactVersionedCounter:

• for comments&worklogs expect compactUnVersionedCounter << compactVersionedCounter
• for issues expect compactUnVersionedCounter ~ 0, can be > 0 only just after ZDU
