Amazon Elasticsearch Service support for Elasticsearch 5.1

The Amazon Elasticsearch Service is a fully managed service that provides easier deployment, operation, and scale for the Elasticsearch open-source search and analytics engine. We are excited to announce that Amazon Elasticsearch Service now supports Elasticsearch 5.1 and Kibana 5.1.

Elasticsearch 5 comes with a ton of new features and enhancements that customers can now take advantage of in Amazon Elasticsearch service. Elements of the Elasticsearch 5 release are as follow:

  • Indexing performance: Improved Indexing throughput with updates to lock implementation & async translog fsyncing
  • Ingestion Pipelines: Incoming data can be sent to a pipeline that applies a series of ingestion processors, allowing transformation to the exact data you want to have in your search index. There are twenty processors included, from simple appending to complex regex applications
  • Painless scripting: Amazon Elasticsearch Service supports Painless, a new secure and performant scripting language for Elasticsearch 5. You can use scripting to change the precedence of search results, delete index fields by query, modify search results to return specific fields, and more.
  • New data structures: Lucene 6 data structures, new data types; half_float, text, keyword, and more complete support for dots-in-fieldnames
  • Search and Aggregations: Refactored search API, BM25 relevance calculations, Instant Aggregations, improvements to histogram aggregations & terms aggregations, and rewritten percolator & completion suggester
  • User experience: Strict settings and body & query string parameter validation, index management improvement, default deprecation logging, new shard allocation API, and new indices efficiency pattern for rollover & shrink APIs
  • Java REST client: simple HTTP/REST Java client that works with Java 7 and handles retry on node failure, as well as, round-robin, sniffing, and logging of requests
  • Other improvements: Lazy unicast hosts DNS lookup, automatic parallel tasking of reindex, update-by-query, delete-by-query, and search cancellation by task management API
