Activate compression :
ALTER TABLE 'test', {NAME=>'mycolumnfamily', COMPRESSION=>'SNAPPY'}
Data block encoding of keys/values
ALTER TABLE 'test', {NAME=>'mycolumnfamily', DATA_BLOCK_ENCODING => 'FAST_DIFF'}
Change Split policy for a table (for Hbase 0.94+ the default Split policy changed from ConstantSizeRegionSplitPolicy (based on hbase.hregion.max.filesize) to IncreasingToUpperBoundRegionSplitPolicy)
alter 'access_demo', {METHOD => 'table_att', CONFIGURATION => {'SPLIT_POLICY' => 'org.apache.hadoop.hbase.regionserver.ConstantSizeRegionSplitPolicy'}}Remember split will occur if the data size of a ColumnFamily gets bigger than the number defined by the policy.
So, what do you think ?
