1. Use Elastic Search for exposing enterprise wide search API.

Date: 2018-05-20

Status

Accepted

Context

There is a need of having an API exposed which can be used to search enterprise wide common data model.

The data currently resides in a RDBMS database, it is difficult to expose micro-services directly querying out of RDBMS databases since the application runs out the same environment.

There are options like ElasticSearch or Solr where data can be replicated.

Decision

Use ElasticSearch for data indexing

Consequences

Data needs to be replicated across the ElasticSearch cluster. This separate cluster needs proper maintenance.

• Near-real time data replication is required.
• Additional cost of maintaining the ElasticSearch environments
