--------------------------------------
Summary: Replication Log Writer
Key: PHOENIX-7567
URL: https://issues.apache.org/jira/browse/PHOENIX-7567
Project: Phoenix
Issue Type: Sub-task
Reporter: Kadir Ozdemir
Assignee: Tanuj Khurana
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 Replication Log Writer.
