Hi all,

I have to process 1M records and download 1M records.

So is it practical to use a bucket size of 1Million so that when i download CSV report , it must have 1 Million documents?

Or is there another approach for this?

I don't think you can do that with Kibana (but I may be wrong). To download such large amount of data you can take a look to this other post

> Hi, guy's How can i download all the data of an index in elasticsearch? it downloads the CSV but it does not show all the data, I need to download the whole index, please help me?

with ideas on using Elasticsearch API directly (scrolling, paged search, etc) or third party tooling.
