----------------------------------
Summary: The batch size of cleaning expired mob files should have
an upper bound
Key: HBASE-27125
URL: https://issues.apache.org/jira/browse/HBASE-27125
Project: HBase
Issue Type: Improvement
Components: mob
Affects Versions: 2.4.12
Reporter: Xiaolin Ha
Assignee: Xiaolin Ha
Fix For: 2.5.0, 2.6.0, 3.0.0-alpha-3, 2.4.13
Currently the cleaning logic for expired mob files is adding all the deletable
files in one directory to a list in memory and then archiving all the files in
the list. But when there are millions of files need to delete, the list will be
huge and make great heap memory pressure to the master.
