Hello,

Is it possible to stream in real time indexed data as it comes in based on a filter using ES? Essentially I'd like to build a "live scroll" - I realise I can poll the data every X seconds and retrieve an updte based on last date, but is there some sort of a push API or streamed read API which updates in real time?

thanks!

If you mean something like the Changes API in CouchDB, then this is still not available just yet.

The core feature required to make it happen, named Sequence ID, is already available. Check this for more information: [https://www.elastic.co/blog/elasticsearch-sequence-ids-6-0](https://www.elastic.co/blog/elasticsearch-sequence-ids-6-0)
