This Week in Elasticsearch - October 30, 2013

Par Alexander Reelsen

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

  • We upgraded to Lucene 4.5.1 (commit, 0.90 & master)
  • The Transport mechanism now has a separate channel for recovery, so it wont collide with bulk requests (#3954, 0.90 & master)
  • Fielddata was refactored, simplified and therefore now is a bit faster (commit, 0.90 & master)
  • The windows service script now detects JREs, supports a stop timeout and a startup mode (#3938, #3962, #3928, 0.90 & master)
  • Highlighting can return excerpt with no highlights (#1171, 0.90 & master)
  • Fixed a NullPointerException in multi_match query when using lenient and field weight (#3797, 0.90 & master)
  • A new highlighter implementation called PostingsHighlighter is now supported (#3704, 0.90 & master)
  • CompletionFieldMapper returns an error if weight is no integer (#3977, 0.90 & master)
  • The has_child query could cause an infinite loop (100% CPU) when used in bool query (#3955, 0.90 & master)
  • Rename and document index.mapping.date.parse_upper_inclusive setting for date fields (#3914, 0.90 & master)
  • PreBuilt analyzers are now versioned on index creation (#3790, 0.90 & master)
  • mget API supports global routing parameter (#3996, 0.90 & master)
  • The cat API got a recovery information endpoint (#3969, master only)
  • Nodes stats: Path, dev and mount fields can now be retrieved using the Java API (#4004, 0.90 & master)
  • When a node completes recovering a shard, a message is sent to master. If the master is not available, it now is ensured to be sent again (#4009, 0.90 & master)

Call for Speakers and Community Organizers

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.

Where to Find You

Are you hosting an Elasticsearch meetup or giving a talk about Elasticsearch? We would love to know so we can feature that information in future editions of This Week in Elasticsearch. Just let our Community Manager know what you're up to and we're happy to help promote your efforts.

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.
