It's called beta. I do need people interested in using it to try it out *seriously*, though. Chris hit quite a wall even when testing it for a while. I've got some data from that but the lesson is: don't think it's ready for (your) production if you haven't run it in (your) production successfully. >> - Does it bring speed improvements over regular ZEO setup (I don't >> think so) ? > > No. It is currently 5 times slower when tested with zodbshootout. And there will likely never will be speed improvements over regular ZEO. I was a bit shocked when I looked at the actual slowness, but then again, I didn't think about performance at all. (In standalone mode there is a slight chance that you can load read-requests off to multiple backend servers. Haven't tried it, though. And it won't be available in co-op mode. >> - Does it work with blobs ? I will have a blob directory shared >> between different servers.

(You wouldn't go editing that data with your editor, would you?)

[ZODB-Dev] Status of gocept.zeoraid
Hello, One of my customers would like to use gocept.zeoraid in production. So him, and I have some questions: - Is it stable enough to be used in production ? - Does it bring speed improvements over regular ZEO setup (I don't think so) ? - Does it work with blobs ? I will have a blob directory shared between different servers. Can I use it to access and edit directly the blob in that directory ?

VACUUM FULL is almost never a good idea; autovac should be sufficient for most needs, and can be tweaked to meet particular performance issues. I have had very good results doing a CLUSTER after an initial zodbconvert run to significantly reduce the size of the database. I highly recommend doing CLUSTER after any large data loads.
