Subject: Re: Uncompress / re-compress of messages in the message server
Yes, your understanding is correct. The reason we have to recompress the
messages is to assign a unique offset to messages inside a compressed
message. Some preliminary load testing shows 30% increase in CPU, but that
is using GZIP which is known to be CPU intensive. By this week, we will
know the CPU usage for a lighter compression codec like Snappy. Will post
the results on the mailing list.
