Hello! I use MySQL as my primary datastore and use Elasticsearch to further
index the documents.
My problem is keeping the data in ES in sync with MySQL.
Currently I have two methods in mind:
- whenever add or update an entry in MySQL, do the action together in ES.
- Do some cron jobs that periodically keep ES in sync with the data in
For method 2 I wonder how can I check if an entry is already indexed in
Elasticsearch. And would it be efficient at all if I have to check every
entry to see if it is updated?
I am new to the technology and I am afraid I had missed some really obvious
and established solutions here. Or otherwise the "normal" way this
situation is handled?
