| Description |

Would be nice to have a balancing strategy that uses the working set estimator to pick chunks to migrate based on trying to evenly distribute the working set across shards. |

Taking out of PM-631 and placing in "Needs Scheduling" since we have closed PM-631 as won't do |

I don't think we need storage by chunk first. Simply moving (active) chunks to the shard with the most effective working set will do it. |

Having a way to group document on-disk order by chunk is likely a prerequisite for this. |
