Subject [jira] [Resolved] (CASSANDRA-6804) Consolidate on-disk and NativeCell layouts so that reads from disk require less memory
Date Mon, 30 Jun 2014 16:08:24 GMT

     [ https://issues.apache.org/jira/browse/CASSANDRA-6804?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Benedict resolved CASSANDRA-6804.
---------------------------------

    Resolution: Won't Fix

CASSANDRA-7447 probably makes this impossible, or at least undesirable, since we will not
store all necessary data for a single cell contiguously.

> If the on-disk Cell representation were the same as we use for NativeCell, we could easily
allocate a NativeCell instead of a BufferCell, immediately reducing the amount of garbage
generated on reads. With further work we may also be able to reach a zero-copy allocation
as well, reducing further the read costs.
