Primarily this will allow the next generation of load balancing to work. Something at a level above MemStore and LruBlockCache needs to manage and divide up the available resources of a regionserver. The block cache now supports dynamic resizing and parameter configuration. Params are also passed in to the constructor, as supposed to being hard-coded / pulled from confs within MemStore itself. -- This message is automatically generated by JIRA. - You can reply to this email to add a comment to the issue online.
