Agreed. It would be nice to see both a single-master and multi-master server included in our main tree and a clear description of when to use each. The confusion over the various replication solutions and their strengths/weaknesses is a major problem.
I always felt a clearer README for rserv would help greatly. We do get lots of questions about how to get it working. README.rserv goes over the major 'toolset' items and describes a demo, but that is it. (I don't even know what the 'toolset' items are or how to access them, at least from reading the README.) I thought of doing the README improvements myself, but because I didn't write it, I left it alone. --------------------------------------------------------------------------- Thomas Lockhart wrote: > ... > > rserver only does single-master, while most people want multi-master. > > As you probably know, rserv is not limited to only a single instance of > a single master.
