MDMS (Master Data Management Service)
Overview
One of the applications in the Digit core group of services aims to reduce the time spent by developers on writing codes to store and fetch master data ( primary data needed for module functionality ) which doesn’t have any business logic associated with them. Instead of writing APIs, creating tables in every different service to store and retrieve data that is seldom changed MDMS service keeps them at a single location for all modules and provides data on will with the help of no more than three lines of configuration.

Deploy the latest version of Mdms-service
Add conf path for the file location
Add master config JSON path
Integration Details
Integration Scope
The MDMS service provides ease of access to master data for any service.
Integration Benefits
No time spent writing repetitive codes with no business logic.
Steps to Integration
To integrate, host of egov-mdms-service should be overwritten in helm chart
egov-mdms-service/v1/_search should be added as the search endpoint for searching master data.
Mdms client from eGov snapshots should be added as mvn entity in pom.xml for ease of access since it provides mdms request pojos.
