Re: [ZODB-Dev] Can RelStorage be used as a ZEO Storage back-end?

2010-10-25 Thread Alan Runyan
 I'm starting to dig into the code, but perhaps this can
 be answered quickly: can RelStorage be used in place of
 FileStorage for ZEO storage?

My understanding is Yes.  Try it.  IIRC you can even use
a ZEO storage in place of a FileStorage.  You may want
to specify what version of python, zodb you are using.

It should work if a single ZEO server is the only client of RelStorage.

 I work with a product that has a number of dependencies
 upon ZEO, directly (Zenoss).  Several months down the
 road, the are migrating from ZEO to RelStorage.  In the
 meantime, I would like to see if I can just drop RelStorage
 in behind ZEO as part of a cross-site HA strategy.

In that case, it sounds like you want to set up multiple ZEO servers as 
clients of RelStorage.  In that configuration, I suspect the ZEO servers 
would not update each other reliably.

I haven't tried Zenoss yet, but surely it can be configured to open a 
storage other than ZEO.
