Is there some sort of preproduction staging mechanism (reindexing takes quite some time)

Elastic Stack Elasticsearch
1

Hi there,

I'm currently evaluating Elasticsearch for our project. In this project we want to completely reindex our database from time to time, which will probably take a few hours up to a couple of days.
This must not affect the database in production, as users are working with the system 24/7.

And here is my question:

  • Is there a best practice around how to achieve this?

Any hints or keywords to search for highly appreciated.

Kind regards
Tom

P.S.: My current toughts on this:

  • Should we index the data into another cluster, node or index?
  • Can we replicate it into our live system?
  • Should we write data with some sort of notYetVisible boolean?
