------------------------------------
Summary: Generic NamedQueue framework for recent in-memory history
(refactor slowlog)
Key: HBASE-24718
URL: https://issues.apache.org/jira/browse/HBASE-24718
Project: HBase
Issue Type: Sub-task
Reporter: Viraj Jasani
Assignee: Viraj Jasani
As per the discussion on parent jira, we should come up with named queue
(online ring buffer) to serve recent history for multiple use-cases like
slowlog, balancer decision, other region activities e.g flush, compaction,
split, merge etc.
Since we already have slow/large rpc logs in ring buffer (HBASE-22978), as part
of this Jira, the proposal is to refactor slowlog provider to get generic
payload for ring buffer and based on event type (slow_log is the only one for
now), we can have separate internal in-memory queues.
After this refactor, it should be relatively simpler to use the same framework
and create more cases like parent Jira (balancer decision in ring buffer).
