> A Sharding Split Policy For Load-Sharing Index Writes
> -----------------------------------------------------

> Key: LUCENE-2435
> URL: https://issues.apache.org/jira/browse/LUCENE-2435

> (Please note that the feature described in LUCENE-2425 is required reading
> for this issue.)
> The sharding split policy builds on the remoting split policy, treating each
> sub-index as a shard of the split index. Optionally, the super-index on which
> the split writer is built may also be considered to be a shard. The
> motivation for this policy is to allow a given index to be partitioned across
> multiple nodes (that define a cluster), which helps to (a) load-balance
> document writes across the nodes in that cluster and (b) serve search
> requests from a (narrower) set of sub-indices (that the split rule routes the
> query to).
> Unlike other sharding solutions for Lucene, this approach gives users the
> ability to (a) pick and choose the types of directories underlying the
> mirror, and (b) add/remove shards on the fly.
