Release Note:

Hide
With ~~HBASE-8176~~("Dynamic Schema Configurations"), we can define table/column family specific configuration by HColumnDescriptor.setValue() or HTableDescriptor.setValue(). We can also do this easily in hbase shell.

Change the table-scope by set attribute CONFIG like this:
alter 'test', METHOD => 'table_att', CONFIG => {'hbase.hstore.compaction.min' => '5'}

Change the column family config by set attribute CONFIG like this:
alter 'test', NAME => 'f', CONFIG => {'hbase.hstore.compaction.min' => '5'}

With ~~HBASE-5335~~, we can support per-table configuration and per-family configurations.

We can use it to customize the compaction on table/family basis, customize the flush, and etc..
