-------------------------------------
Assignee: Vincent Poon
> Make KillServerOnFailurePolicy a configurable option in
> PhoenixIndexFailurePolicy
> ---------------------------------------------------------------------------------
>
> Key: PHOENIX-4977
> URL: https://issues.apache.org/jira/browse/PHOENIX-4977
> Project: Phoenix
> Issue Type: Bug
> Affects Versions: 4.14.0
> Reporter: Vincent Poon
> Assignee: Vincent Poon
> Priority: Major
>
> Currently PhoenixIndexFailurePolicy, which is the default policy, delegates
> to KillServerOnFailurePolicy. This is hardcoded in the constructor.
> Apparently this was added for a specific use case,
> BLOCK_DATA_TABLE_WRITES_ON_WRITE_FAILURE, and the policy itself derives from
> the days where forcing a RS kill was in effect the way to 'rebuild' the index
> via WAL replay.
> There are still cases where it's applicable, such as when Syscat itself
> cannot be updated in order to e.g. disable an index. However, killing the RS
> may be too aggressive for some, who might prefer a temporarily out of sync
> index to a potentially cascading wave of aborts.
> We should add a config option to control this.
