Subject [jira] [Updated] (HBASE-10655) ByteBuf-fronted slab allocator for on- and off-heap cellblock storage
Date Mon, 03 Mar 2014 03:02:20 GMT

     [ https://issues.apache.org/jira/browse/HBASE-10655?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Andrew Purtell updated HBASE-10655:
-----------------------------------

    Description: Our ByteRange interface has some nice properties such as a compareTo method
using hbase-friendly unsigned byte comparison. This can be backed by either on-heap or off-heap
byte buffers. Consider an allocator that internally allocaetes huge on or off-heap slabs and
hands out ByteRangers over portions of those arenas. Keep it as simple as possible, optimized
for HBase needs. Can be fairly standalone with respect to the rest of the HBase code.
