Elasticsearch features presentation

  1. 1. Elasticsearch Features
  2. 2. Distributed and Highly Available Search Engine. • Each index is fully sharded with a configurable number of shards. • Each shard can have one or more replicas. • Read / Search operations performed on either one of the replica shard.
  3. 3. Multi Tenant with Multi Types. • Support for more than one index. • Support for more than one type per index. • Index level configuration (number of shards, index storage, …).
  4. 4. Various set of APIs • HTTP RESTful API • Native Java API. • All APIs perform automatic node operation rerouting.
  5. 5. Reliable, Asynchronous Write Behind for long term persistency. • Elasticsearch puts your data safety first. Document changes are recorded in transaction logs on multiple nodes in the cluster to minimise the chance of any data loss.
  6. 6. Real Time Search. • Data flows into your system all the time. The question is … how quickly can that data become an insight? With Elasticsearch, realtime is the only time.
  7. 7. Built on top of Lucene • Each shard is a fully functional Lucene index • All the power of Lucene easily exposed through simple configuration / plugins.
  8. 8. Open Source under Apache 2 License • Elasticsearch can be downloaded, used and modified free of charge. It is available under the Apache 2 license, one of the most flexible open source licenses available.
