Explains its purpose and surrounding context a little more, including a note that this should never be necessary (i.e. if you find you need it, that's a bug).

=== Reset desired balance API

NOTE: {cloud-only}
|
|
|
|
Discards the current desired balance and computes a new desired balance starting from the current allocation of shards.
|
|
This can sometimes help {es} find a desired balance which needs fewer shard movements to achieve, especially if the
|
|
cluster has experienced changes so substantial that the current desired balance is no longer optimal without {es} having
|
|
detected that the current desired balance will take more shard movements to achieve than needed. However, this API
|
|
imposes a heavy load on the elected master node and may not always have the expected effect. Calling this API should
|
|
never be necessary. Consider instead <<shards-rebalancing-heuristics,increasing the value of
|
|
`cluster.routing.allocation.balance.threshold`>> to avoid excessive shard movements.
