Subject [jira] [Commented] (CASSANDRA-4400) Correctly catch exception when Snappy cannot be loaded
Date Mon, 10 Dec 2012 15:31:21 GMT

    [ https://issues.apache.org/jira/browse/CASSANDRA-4400?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13527998#comment-13527998
] 

Sylvain Lebresne commented on CASSANDRA-4400:
---------------------------------------------

bq. Is there a reason Cassandra's not using the pure Java version of Snappy?

An very quick look at those benchmarks seems to suggest that the JNI impl is still faster
on read, which is what we mainly care about. That being said, it wouldn't be crazy to fallback
to the pure Java version if the JNI one can't be loaded, provided this is not too complicated
to do. At least patches are welcome :)
