How to enable read-aware data distributor?

Using FoundationDB
1

Hi!

This document (https://github.com/apple/foundationdb/blob/main/design/data-distributor-internals.md) appears to indicate that read-aware data distributor is available as of 7.2. It doesn’t mention how to enable it however. I found this (https://github.com/apple/foundationdb/blob/5eae3be195ee5c1302878459d3d1d34282b1ee60/fdbcli/DataDistributionCommand.actor.cpp#L114C13-L115) cli command and tried running datadistribution enable rebalance_read but as far as I can tell it didn’t trigger any data movement. The release notes for 7.2 also don’t mention read-aware data distributor (Release Notes — FoundationDB 7.2). So I was wondering:

  1. Is this actually available in 7.2?
  2. If it is, how do I enable it?

Thanks.
