We are using Change Data Capture (CDC) to sync up data between my source database to elasticsearch.
Should i do re-index, is it needed?
If I do re-index will it impact the performance of elastic users?
if the performance is hit, then what is the work-around?
Apologies, if there is any other similar thread on the same topic. Because I couldn't find that thread.
Indexing does impact the cluster as it takes up resources, to what extent depends on your cluster though. If you don't want that to happen then you should scale out.
