Refreshing the ElasticSearch index from RDBMS using Spring Data

问题

I have the following setup :

• Mysql RDBMS server
• Elastic Search Server

My requirement is to copy data periodically from MYSQL RDBMS and update Elastic server with it.Currently i am following the approach below :

• A Batch Job which reads all data from MYSQL using Spring Data Jpa
• It then pushes all data to elastic server using spring data elastic

This approach is very cumbersome and not efficient.Is there a way where i can read only the updated values using spring data and update the index accordingly in elastic.

Using jdbc-river etc is not an option for me as the application uses Spring data elastic to get data and search over elastic search,with jdbc-river it will not be able to function properly i think.
