Hello all, I'm trying to incorporate ElasticSearch with our existing MongoDB
Currently we have a mongo collection separated to three mongo shards.
Does that mean I have to use three ElasticSearch clusters for each of them?
You shouldn't need 3 clusters. You might need more than one
Elasticsearch server to handle the load, but that depends on a lot of
factors, mainly about how your data, queries and hardware look like.
Is there a simpler practice to just use a single ElasticSearch cluster only?
The easiest way to index data from your MongoDB cluster to an
Elasticsearch cluster is using the MongoDB river:
There's a nice Wiki there as well, with instructions:
