Multi data center replication


We have two ElasticSearch clusters - one on the east coast and one on
the west coast, representing the same index. The goal is fault
tolerance in case one of our data center goes down.

Since the current version of ElasticSearch doesn't seem to be multi
data-center aware like Cassandra, we have a backend daemon that feeds
any updates done on the east coast, to the west coast ElasticSearch
and vice versa.

Wondering if others who are using ElasticSearch in a multi data-center
configuration are using a similar setup or if there's a simpler

We are planning to implement a similiar configuration to have multi data center. Do you know how the licensing works for the other inactive (ie active-passive) data centers?
