Subject [jira] [Updated] (CASSANDRA-8714) row-cache: use preloaded jemalloc w/ Unsafe
Date Tue, 24 Feb 2015 17:08:04 GMT

     [ https://issues.apache.org/jira/browse/CASSANDRA-8714?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Robert Stupp updated CASSANDRA-8714:
------------------------------------
    Attachment: 8714-4.txt

Attached patch 8714-4.txt changes:
* revert {{getByteBuffer()}} change
* OHC 0.3.4 (use faster off-heap allocation method, too)
* move config stuff from {{bin/cassandra}} to {{conf/cassandra-env.sh}}

[~JoshuaMcKenzie] it would be interesting to see, how Windows's malloc compares to jemalloc-win32
over JNA.

Unfortunately there's nothing like {{LD_PRELOAD}} on Win. Although there are [some approaches
how to do it|https://en.wikipedia.org/wiki/DLL_injection], none of them really convinces me.

> Using jemalloc via Java's {{Unsafe}} is a better alternative on Linux than using jemalloc
via JNA.
