I am completely naive to ELK stack. My requirement is I am creating indexes on ES using logstash via JDBC plugin. I am indexing DB table to ES. If DB tables modified or new data inserted then only modified and inserted rows should be indexed in ES. example an Employee table contains 1000 records. Logstash indexed it by named empRec in ES. After some time 5 records of 1000 get modified in DB then only 5 records under empRec index should be modified immediately. IF let say 15 employee gets added then It should be reflected ES indexed also.
How to achieve this in ELK stack? In brief whenever underlying DB changes corresponding ES index should get updated modified.
I am using the latest version of ELK stack i.e 7.0.1
