---------------------------------
Summary: Need to find a way to limit the number of proc wal files
Key: HBASE-21254
URL: https://issues.apache.org/jira/browse/HBASE-21254
Project: HBase
Issue Type: Sub-task
Components: proc-v2
Reporter: Duo Zhang
Fix For: 3.0.0, 2.2.0
For regionserver, we have a max wal file limitation, if we reach the
limitation, we will trigger a flush on specific regions so that we can delete
old wal files. But for proc wals, we do not have this mechanism, and it will be
worse after HBASE-21233, as if there is an old procedure which can not make
progress and do not persist its state, we need to keep the old proc wal file
for ever...
