This is useful for protecting against hardware failures – if all of your shards are replicated, then the failure of one node in your cluster will not impact availability. ReplicaĪ replica is simply a copy of a shard. Sharding helps you scale this data beyond one machine by breaking your index up into multiple parts and storing it on multiple nodes.īeyond allowing for more storage, shards also allow for better performance, because data in the same index can be searched by multiple nodes at the same time. The example Elasticsearch index we build today will be really small, but many indexes can get quite large and it isn’t uncommon at all to have Elasticsearch index with multiple terabytes of data in them. It is somewhat similar in function to a database or schema in the traditional database world. ![]() IndexĪn index is a collection of related types of documents.

It will allow you to identify the best talents very easily! Basic Terms DocumentĪ document is the basic record you store in Elasticsearch.
