In our e-commerce company, the DevOps engineer were facing a lot of trouble managing certain tables in MySQL namely logs_users, logs_actions which store logs of each visitor who comes to
their e-commerce store. In an year's time the table size grew to 70GB. We hired a senior DevOps and when he analyzed the situation he immediately asked engineers to migrate these
tables to elastic search. Migration took 7 days to complete, but engineers are not sure if it was successful. How should we test it and make sure it was successful?
