> Key: PHOENIX-7567
> URL: https://issues.apache.org/jira/browse/PHOENIX-7567
> Project: Phoenix
> Issue Type: Sub-task
> Reporter: Kadir Ozdemir
> Assignee: Andrew Kyle Purtell
> Priority: Major
> Fix For: PHOENIX-7562-feature
>
>
> As described in the design document for PHOENIX-7562, Replication Log Writer
> ensures that every data mutation occurring in the source cluster is durably
> recorded in replication logs. It synchronously writes these logs to the
> target cluster’s HDFS filesystem when that HDFS volume is available and
> performing well. -If the target cluster’s HDFS volume becomes unavailable or
> experiences degraded write performance, the writer seamlessly switches to a
> local mode, writing logs into the source cluster’s HDFS filesystem, instead.-
> This subtask is to design and implement only the synchronous parts of the
> Replication Log Writer.
