James Taylor updated PHOENIX-4130:
----------------------------------
Fix Version/s: 4.14.0
> Avoid server retries for mutable indexes
> ----------------------------------------
>
> Key: PHOENIX-4130
> URL: https://issues.apache.org/jira/browse/PHOENIX-4130
> Project: Phoenix
> Issue Type: Improvement
> Reporter: Lars Hofhansl
> Assignee: Vincent Poon
> Fix For: 4.14.0
>
>
> Had some discussions with [~jamestaylor], [~samarthjain], and [~vincentpoon],
> during which I suggested that we can possibly eliminate retry loops happening
> at the server that cause the handler threads to be stuck potentially for
> quite a while (at least multiple seconds to ride over common scenarios like
> splits).
> Instead we can do the retries at the Phoenix client that.
> So:
> # The index updates are not retried on the server. (retries = 0)
> # A failed index update would set the failed index timestamp but leave the
> index enabled.
> # Now the handler thread is done, it throws an appropriate exception back to
> the client.
> # The Phoenix client can now retry. When those retries fail the index is
> disabled (if the policy dictates that) and throw the exception back to its
> caller.
> So no more waiting is needed on the server, handler threads are freed
> immediately.
