Merging, Packing, and Splitting Table Regions

You can use maprcli commands to mege, pack, and split table regions.

Merging regions
Use the command table region merge to reduce the number of regions that contain the data of a table.
Packing regions
Use the command table region pack to reclaim disk space manually from regions of a table or to avoid read amplification, overriding MapR-DB's periodic automatic region packing.
Splitting regions
Use the command table region split to split a region of a table, overriding MapR-DB's automatic region splitting.
