Re: [Sqlrelay-discussion] Client proto changes

[David M. <dav...@fi...>]

Hi Georgy,

Good question.  The client-server protocol has changed over the years. 
Most versions are cross-compatible, but in version 0.49, there was a 
fairly significant change that improved performance by removing a 
client-server round-trip, so unfortunately 0.51 and 0.46 are not compatible.

In the not-yet-released 0.54, I'm adding another change too, a protocol 
version flag.  Whenever 1.0 comes out, all 1.X versions should be 
protocol-compatible.  2.x should support the 2.X and 1.X protocols, and 
so on.  That's the plan, at least.

Sorry for the bad news.

Dave
