Subject [jira] [Updated] (CASSANDRA-5199) Avoid serializing to byte[] on commitlog append
Date Wed, 30 Jan 2013 04:09:14 GMT


Jonathan Ellis updated CASSANDRA-5199:

    Attachment: 5199-2.0.txt

2.0 version adds ByteBufferOutputStream and ChecksummedOutputStream to get rid of byte[] serialization
entirely.  Also fixes mutation-length checksumming to include the entire length, not just
the first eight bits.

> We used to avoid re-serializing RowMutations by caching the byte[] that we read off the
wire.  We don't do that anymore since we fixed MessagingService to not create intermediate
byte[].  So we should serialize the mutation directly to the commitlog.
