Hi.
I have a really big index with 100 millions of documents.
I want to add some new fields, change existing ones and delete the redundant ones by applying explicit index. I will also use alias to switch the indiced.
--> existing_index - ALIAS
--> new_index -> ALIAS
But the problem is that I am pulling the new documents continuously from a database. In this case I have to stop Logstash to write to existing index, then reindex it and switch alias.
Is there any better way to do it without stopping Logstash?
Thanks.
