With this PR we will be adding an additional index setting indices.replication.max_bytes_per_sec to control the max bytes per second for node-node segment replication.

This page should be updated to reflect this new setting.

I am thinking:

indices.replication.max_bytes_per_sec (String): Limits the total inbound and outbound replication traffic for each node. This applies to segment replication between nodes. Default is tied to the set value of indices.recovery.max_bytes_per_sec, which is by default 40mb. If you set the replication traffic value to less than or equal to 0mb, rate limiting will be disabled, which causes replication data to be transferred at the highest possible rate.

What other resources are available? Provide links to related issues, POCs, steps for testing, etc.

Thanks, @mch2 ! I assume we are targeting 2.14?

[mch2]

@hdhalter Yup this will be introduced starting 2.14. Thanks
