Currently I am performing full text search on MongoDB but I would love to use Elasticsearch for the same. My primary data source is MongoDB. Right now I am not able find a suitable/reliable sync tool for MongoDB->Elasticsearch.
There used to be a tool called elasticsearch-river-mongodb [1] which is deprecated now.
Also, there is no official logstash input plugin for MongoDB

What tool do you use to reliably sync MongoDB collections with Elasticsearch?
