Question

What are the advantage and disadvantage of Elasticsearch?

Answer 1

Advantages

• Elasticsearch is developed on Java, which makes it compatible on almost every platform.

• Elasticsearch is real time, in other words after one second the added document is searchable in this engine

• Elasticsearch is distributed, which makes it easy to scale and integrate in any big organization.

• Creating full backups are easy by using the concept of gateway, which is present in Elasticsearch.

• Handling multi-tenancy is very easy in Elasticsearch when compared to Apache Solr.

• Elasticsearch uses JSON objects as responses, which makes it possible to invoke the Elasticsearch server with a large number of different programming languages.

• Elasticsearch supports almost every document type except those that do not support text rendering.

Disadvantages

• Elasticsearch does not have multi-language support in terms of handling request and response data (only possible in JSON) unlike in Apache Solr, where it is possible in CSV, XML and JSON formats.

• Occasionally, Elasticsearch has a problem of Split brain situations.
