Using postCommit event to swap cores

[simon <si...@simondo.com>]

Hi there,

I have solr configured with 2 cores, "live" and "standby".  "Live" is
used to service search requests from our users.  "Standby" is used to
rebuild the index from scratch each night.  Currently I have the
postCommit hook setup to swap the two cores over as soon as the indexing
on "standby" is complete. 

It seems to work well on my development box, but I have not seen this
approach discussed elsewhere so I was wondering if I was missing
something here.

Feedback gratefully received!

Simon

Depending on the size of your index (or the number of indexes you have) 
and update frequency, you can even offload indexing to a dedicated 
server and replicate from that. Works very well for us and we have about 
8 cores.

Another way to do this is to set up the "live" core to do replication
from the "standby" core. Replication should work this way, between
different cores in the same Solr instance. This is cleaner than
swapping the two cores.
