Elasticsearch features presentation

1. Elasticsearch Features

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. 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. Various set of APIs
• HTTP RESTful API
• Native Java API.
• All APIs perform automatic node operation
rerouting.

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. 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. 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. 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.
