Is there any support for predicate pushdown in elasticsearch? I am using elasticsearch with Flink for stream processing.

 org.apache.flink flink-connector-elasticsearch5\_2.10 1.3.1

Thanks

Not directly.

But if I am understanding the concept correctly ([based on this](http://www.dbms2.com/2014/07/15/the-point-of-predicate-pushdown/)), then Elasticsearch does this anyway by running each query only on the applicable shard.
