Subject [jira] Commented: (CASSANDRA-47) SSTable compression
Date Mon, 31 Aug 2009 08:15:32 GMT


Johan Oskarsson commented on CASSANDRA-47:

While Lzo is great, it is unfortunately not compatible with the Apache license. They had to
remove it from Hadoop, see HADOOP-4874. In that ticket they mention a couple of alternatives
such as or lzf

It would be possible to do what Hadoop has done and released the lzo bindings separately,
but that would make it harder for users to find and use.

a good trade).
