Rollover: from Hot to Warm nodes - limit per 'max_concurrent_file_chunks' and/or 'max_bytes_per_sec'?

Elastic Stack Elasticsearch
1

I have hot phase indexes on certain elasticsearch nodes.

Is it possible to set the index rollover data transmission rate on data flow: hot nodes => warm nodes?

I mean, 'max_concurrent_file_chunks' and/or 'max_bytes_per_sec' as for recovery?

What possibilities do we have to define and manipulate the speed of such data flow?

2

Yes, those two settings are the ones to use. "Recovery" is the name of the process used to move shards between nodes so these settings apply.

3

Is there a limit to the maximum amount of 'max_concurrent_file_chunks' per cluster?
Is there any option?

4

Yes, the limit for max_concurrent_file_chunks is 5.

5

But I mean limit not per node, but per cluster.

Is it possible to set this limit per cluster? For example, equal to 8?

6

No, there's no cluster-wide limit. I'm not sure I understand why you would want such a thing.
