Subject [jira] [Commented] (CASSANDRA-3015) Inter-Node Compression
Date Sat, 13 Aug 2011 15:14:41 GMT

Pavel Yaskevich commented on CASSANDRA-3015:
--------------------------------------------

If we want to go with compression for streaming there is no need to use channel any more because
it was only useful in a sense of DMA data transfer, losing that dependency also gives us benefit
of joining paths of handling of the compressed and normal SSTables files.

After taking a look at the SSL part of the streaming code I think we can make write method
private because the difference between SSL and normal transfer is only socket type, o.a.c.security.streaming.SSLFileStreamTask
should not care about data condition we send using it, named change also gives us a way to
use SSL over compressed data.

> Although we have CASSANDRA-47 for on-disk the code used for streaming actually sends
un-compressed blocks over the wire. I propose we compress this data.
