Elastic Search for Ruby on Rails

Elasticsearch provides a robust, quiet hypertext transfer protocol interface for assortment and queryinEg knowledge, designed on high of the Apache Lucene library. Right out of the box, it provides scalable , efficient, and strong search, with UTF-8 support. It’s a robust tool for assortment and querying huge amounts of structured knowledge.

Basic Ideas of Elastic search:

Cluster: A cluster may be a assortment of nodes that hold knowledge. It provides assortment and search capabilities across all nodes and is known by a novel name.

Node: A node may be a single server that's a part of the cluster, stores the information, and participates within the cluster’s assortment and search capabilities.

Index: associate index may be a assortment of documents with similar characteristics, like client knowledge or order knowledge. It’s sort of a electronic information service, with mappings that outline multiple sorts.

Type: There are often multiple sorts inside associate index. as an example, in our application we've the GetCount index, that has totally different sections like active user count and inactive user count.

Document:A document may be a basic unit of knowledge that may be indexed. it's sort of a row during a table during a electronic information service, like knowledge for a client or product, and is delineated in JSON format. we are able to have multiple documents in associate index, however they need to be indexed to a kind inside associate index.

Shards and Replicas: associate index will probably store an outsized quantity of knowledge surpassing hardware limits. Elastic Search provides the flexibility to divide indexes into multiple items known as shards, that permits the content to scale horizontally. Elastic Search conjointly permits users to form copies of index shards, that square measure known as replicas.

Elasticsearch also can be used as data store engine, however it's some disadvantages:

Security - Elasticsearch doesn't offer any internal security or access system. the sole thanks to shield metal from external access is with a firewall.

Computation – there's restricted support for advanced computation on the info facet.

Data handiness – knowledge in Elasticsearch is offered in "near real time", - which means that if you submit a comment to a post and refresh the page, it would not show up because the index remains change.

Durability – metal is distributed and comparatively stable, however backups don't seem to be as high priority as in different knowledge store solutions. this can be a crucial thought once Elasticsearch is your primary knowledge store.
