---------------------------------
Summary: compaction bandwidth limit
Key: HBASE-12330
URL: https://issues.apache.org/jira/browse/HBASE-12330
Project: HBase
Issue Type: New Feature
Components: Admin, Compaction
Affects Versions: 0.89-fb
Environment: software platform
Reporter: Ming Chen
Priority: Minor
Fix For: 0.89-fb
Compaction runs to its full speed. This change provides two knobs to limit the
compaction bandwidth:
1 compactBwLimit: the desired max bandwidth per compaction. If the compaction
thread runs too fast, it will be put to sleep for a while;
2. numOfFilesDisableCompactLimit: Limiting the compaction speed will increase
the # of files per store which increases the read latency. This parameter can
disable the compaction limit when the number of files in a store exceeds the
value.
