In our legacy product Compass:2.2.0 is used for searching. Now we are planning to upgrade it to Elastic Search 7.2. Can anyone provide us a few steps or links that can help our cases?
We use PostgreSQL, MySQL, MSSQL and Oracle database in our product based on the customer needs. So I need to know how I can index a whole running database with elasticsearch
Basically, I'd recommend modifying the application layer if possible and send data to elasticsearch in the same "transaction" as you are sending your data to the database.
