What is Elasticsearch?

Elasticsearch is a database which is used to store and manage data that are semi-structured. Let us look at some of its components and then on the benefits of using it.

Cluster

Cluster, in Elasticsearch, is actually storage that contains one or more than one servers. These servers are responsible for holding the entire data.

Index

The documents that are of similar properties are stored in the Index. This could be understood by the example that, the consumer data and the product information could be stored in Index, together. When it comes to identify the index, then unique names are given to each one of them.

Shards

Shards are basically a subset that contains documents from Index. One index could be divided into a lot of shards.

Node

This is a server. It is a single server that holds data. It actively participates in the querying of the cluster.

Benefits of Elasticsearch

  • The benefits of this database manager could be understood by drawing a parallel between the databases managers used earlier. If we say that the data in the earlier database systems could be transferred in the time duration of 10 seconds, then this could transfer the data in 10 ms.
  • It does fast and direct operations. One could get easy access to it. Also, it is very easy to use and handle.
  • It is free from complexities. There are times when a person needs to index more than one document at a time. This particular manager is capable of doing that, very easily.

So, these are the basic things that one must know about Elasticsearch. One thing that you should keep in your mind is that it is not a new thing, but it is evolving with time. So, one should have no second thoughts before using it. Looking to get a depth learning Elasticsearch, then the Udemy best-selling Complete Guide to Elasticsearch course is your choice.
