question about setting block cache size for a column family

["Yu, Libo " <li...@citi.com>]

Hi,

I know hfile.block.cache.size can set a maximum limit on the memory used by block cache.
HColumnDescriptor.setBlockSize() can set the size for a column family. I wonder if it is
possible to set the block size for each table in the configuration file. Thanks.

Regards,

Libo

HColumnDescriptor.setBlockSize() sets Blocksize to use when writing out
storefiles/hfiles
It doesn't affect block cache.

Cheers

You can do this in hbase shell, or in code when you create or modify table.
