------------------------------------
Summary: Option to parallelize restoreStoreFile in
RestoreSnapshotHelper#cloneRegion
Key: HBASE-18256
URL: https://issues.apache.org/jira/browse/HBASE-18256
Project: HBase
Issue Type: Improvement
Components: mob
Affects Versions: 2.0.0-alpha-1
Reporter: huaxiang sun
Assignee: huaxiang sun
Priority: Minor
In one of the MOB case, we found that cloneSnapshot of a MOB enabled table took
very long time. The reason is that for the MOB region, there are lots of MOB
files. It took long time to clone the MOB region. In order to speed up
cloneSnapshot, we will provide an option to parallelize restoreStoreFile in
RestoreSnapshotHelper#cloneRegion, so MOB can take advantage of it. For non-MOB
tables, it will keep the current behavior.
