mygood commented on issue #997: HBASE-23656 [MERGETOOL] HBASE Support Merge region by pattern
URL: https://github.com/apache/hbase/pull/997#issuecomment-572039709
 
 
   Design Objective:
   
   1. Merge empty region
   2. Neat region
   3.  merge expired region
   Usage: bin/hbase onlinemerge [--tableName=] [--startRegion=] [--stopRegion=] [--maxRegionSize=] [--maxRegionCreateTime=] [--numMaxMergePlans=] [--targetRegionCount=] [--printExecutionPlan=] [--configMergePauseTime=]
   
   Options:
   --h or --h print help
   --tableName table name must be not null
   --startRegion start region
   --stopRegion stop region
   --maxRegionSize max region size Unit GB
   --maxRegionCreateTime max Region Create Time yyyy/MM/dd HH:mm:ss
   --numMaxMergePlans num MaxMerge Plans
   --targetRegionCount target Region Count
   --configMergePauseTime config Merge Pause Time In milliseconds
   --printExecutionPlan Value default is true print execution plans false is execution merge
   
   Examples:
   bin/hbase onlinemerge --tableName=test:test1 --startRegion=test:test1,,1576835912332.01d0d6c2b41e204104524d9aec6074fb. --stopRegion=test:test1,bbbbbbbb,1573044786980.0c9b5bd93f3b19eb9bd1a1011ddff66f. --maxRegionSize=0 --maxRegionCreateTime=yyyy/MM/dd HH:mm:ss --numMaxMergePlans=2 --targetRegionCount=4 --printExecutionPlan=false
