Load Balancing and Clustering for Compass?

We are looking at failover mechanisms for our compass implementation. Specifically, we are worried that the server hosting the index could fail and we would need the ability to (hopefully) automatically detect and failover to another machine. Part of this failover would obviously have to include parallel replication of the index on two or more machines.

We know that one way we could do this is to use the JDBC feature of Compass and then take advantage of the databases ability to do this for us. But from what I understand, although we have not tested it, the JDBC configuration is way slower than the local index configuration. But given the need for replication, failover and load balancing, maybe it is the way?

Any advice greatly appreciated!

Hey Mark,

You can read this thread which has an interesting discussion regarding clustering: http://forums.opensymphony.com/thread.jspa?threadID=25296&tstart=60 . Basically, you can go with SAN as well.

I do not have numbers regarding the Jdbc solution (since it is really depends on the database, hardware and so on), but testing it should be really simple since changing to Jdbc storage is just a matter of configuration. If you can share your findings, it would be great as well. I focused on performance when I wrote the JdbcDirectory, but there is probably always room for more :).

Also, if your index is mostly read only, you can simply copy it over to the other box, and schedule your updates (discussed on that thread as well).

Thanks Shay. Weird that using the 'clustering' keyword in the forum search does not display the thread you included. (at least for me)

SAN does not seem like a bad idea. Hopefully sometime in the next couple weeks we can try a test JDBC run and post our findings.

I noticed that, I think that during the migration process, it failed to index it or something. I will see if I can fix it.
