Hello,
Andrew sir: Completely missed that. Thanks :) . csum feature is
introduced in libdrizzle last december I think. So not much blogs on it .
It was around then, yes. It was blogged about on my own blog. If you
are implementing a different way there are some things to note:
1. All events will have a 4byte CRC32 on the end
2. The CRC32 is not rolling through the log, it starts from 0 for each event
3. The client needs to set a user variable (I forget what it is called
now) to say it supports checksums, otherwise the connection is rejected
4. The client should assume that connections to 5.6.1 servers onwards
have checksumming support
Note that I'm not happy about the way the above was implemented in MySQL
(it was very easy to do in a backwards compatible way) but at least they
finally have it now.
Kind Regards
