Currently HRegionInfo also > contains the HTableDescriptor (the schema). That means we store the schema n > times where n is the number of regions in the table. > Additionally, for every region of the same table that the region server has > open, there is a copy of the schema. Thus it is stored in memory once for > each open region. > If HRegionInfo merely contained the table name the HTableDescriptor could be > stored in a separate file and easily found. -- This message is automatically generated by JIRA.
