Load balancing with two sphinx servers

[atomical]

Hi Pat,

Hope you're doing well. Is there a way to load balance sphinx servers with one of these options?

1. Two sphinx searchd instances on separate servers where requests are load balanced between the two.
2. Two sphinx searchd instances on separate servers but one is a backup server that only fields requests when the primary server goes down.
3. The actual index files are in a shared mount that both servers can access.

My main concern is consistency with the indexes and keeping both indexes updated.
