This Week in Elasticsearch - October 09, 2013

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

  • Upgrade to Lucene 4.5 (commit, 0.90 & master)
  • Elasticsearch now uses HPPC instead of trove (commit, 0.90 & master)
  • Better logic ignoring filters when parsing (there is a difference when a filter is empty, one cannot simply do a match all or none filter)  (#3838, 0.90 & master)
  • The @Required annotation has been removed (commit, 0.90 & master)
  • Parsing of completion field content got more strict (commit, 0.90 & master)
  • A race condition when indexing and merging mapping updates from master was fixed (#3844, 0.90 & master)
  • Warm-up of merged segments can be improved without configuring warm-up queries (#3819, 0.90 & master)
  • Calling bin/plugin with wrong parameters could lead to accidental removing of the bin directory (#3847, 0.90 & master)

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


  • Simon Willnauer will speak at GOTO Berlin on "With a hammer in your hand ... Elasticsearch". Simon's talk is scheduled for Friday, October 18th at 11:30 AM and he'll be hanging out with our Community Manager, Leslie Hawthorn in the exhibits hall throughout the conference. Stop by the Elasticsearch stand and say hello!
