> To align with what we have in HStore, I think we also need to add a
StoragePolicy config in TableDescriptor?
For this question, i have tested, we can set table like this:
` alter 'usertable', CONFIGURATION => {'hbase.hregion.block.storage.policy'
=> 'ALL_SSD'}`
Currently CF-level Storage Policy can be set in CF, for example:
`create 'table',{NAME=>'f1',STORAGE_POLICY=>'ALL_SSD'}`
If we wanted to add a StoragePolicy config in TableDescriptor, it would look
like this:
`create 't1', 'f1', REGION_STORAGE_POLICY=>'ALL_SSD', SPLITS_FILE =>
'splits.txt', OWNER => 'johndoe'`
We can see that this option is on par with SPLITS, OWNER, etc. My personal
opinion is that it's not so important, a configuration support is enough, and
it maybe too heavy if we extract it in isolation.
What do you think? @Apache9
