This Week in Elasticsearch - May 21, 2014

Welcome to This Week in Elasticsearch. In this roundup, we try to inform you about the latest and greatest changes in Elasticsearch. We cover what happened in the GitHub repositories, as well as many Elasticsearch events happening worldwide, and give you a small peek into the future of the project.

Elasticsearch Core

Elasticsearch Ecosystem

Here's some more information about what is happening in the ecosystem we are maintaining around the ELK stack - that's Elasticsearch plus Logstash and Kibana - including plugin and driver releases.

We <3 you, too, Grant!

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 Elasticearch, Kibana and Logstash than where you rest your head.
