--------------------------------------
Summary: Use BlockingWaitStrategy for the replication-log Disruptor
Key: PHOENIX-8004
URL: https://issues.apache.org/jira/browse/PHOENIX-8004
Project: Phoenix
Issue Type: Sub-task
Reporter: Tanuj Khurana
Assignee: Tanuj Khurana
The ReplicationLogGroup Disruptor was created with YieldingWaitStrategy, which
busy-spins/yields and pins a CPU core per HA group even when the ring buffer is
idle. Switch to BlockingWaitStrategy, which parks the consumer when the ring is
empty (0 CPU when idle). This matches HBase's own WAL Disruptor (FSHLog), which
uses BlockingWaitStrategy because the HDFS append/sync work dwarfs any wakeup
latency, so spinning makes no sense.
