Elasticsearch Ecosystem

Here's some more information about what is happening in the ecosystem we are maintaining around Elasticsearch, including plugin and driver releases, as well as news about Logstash and Kibana.


Where to find Us


The first ever Elasticsearch Tel Aviv meetup will take place on December 30th, beginning at 7 PM. Join Elasticsearch core developer Uri Boness, who will present on what's new in Elasticsearch 1.0, and Itamar Syn-Hershko, who will discuss Monitoring online conversation at scale using Elasticsearch.


David Pilato will talk about Making sense of your big data in Angers at the 14th of January.


Boaz Leskes will talk about Elasticsearch at 010dev in Rotterdam at the 9th of January.

United Kingdom

Mark Harwood will talk about Elasticsearch 1.0 at QCon night London in London at the 15th of January.

Where to Find You

Our Community Manager, Leslie Hawthorn, is hard at work to help folks create more Elasticsearch meetup groups and to help meetup organizers find more speakers. If you are interested in either effort, take a moment to let her know.

Oh yeah, we're also hiring. If you'd like us to find you for employment purposes, just drop us a note.  We care more about your skill set and passion for Elasticsearch, Kibana and Logstash than where you rest your head.


If you are interested in Elasticsearch training we have courses taught by our core developers coming up in:

  • We're hiring

    Work for a global, distributed team where finding someone like you is just a Zoom meeting away. Flexible work with impact? Development opportunities from the start?
