Adds or removes master-eligible nodes from the voting configuration exclusion list.
If the Elasticsearch security features are enabled, you must have the
managecluster privilege to use this API.
- If the operator privileges feature is enabled, only operator users can use this API.
By default, if there are more than three master-eligible nodes in the cluster and you remove fewer than half of the master-eligible nodes in the cluster at once, the voting configuration automatically shrinks.
If you want to shrink the voting configuration to contain fewer than three nodes or to remove half or more of the master-eligible nodes in the cluster at once, you must use this API to remove departed nodes from the voting configuration manually. It adds an entry for that node in the voting configuration exclusions list. The cluster then tries to reconfigure the voting configuration to remove that node and to prevent it from returning.
If the API fails, you can safely retry it. Only a successful response guarantees that the node has been removed from the voting configuration and will not be reinstated.
Voting exclusions are required only when you remove at least half of the master-eligible nodes from a cluster in a short time period. They are not required when removing master-ineligible nodes or fewer than half of the master-eligible nodes.

(Optional, time units) When adding a voting configuration
exclusion, the API waits for the specified nodes to be excluded from the voting
configuration before returning. The period of time to wait is specified by the
?timeoutquery parameter. If the timeout expires before the appropriate condition is satisfied, the request fails and returns an error. Defaults to
(Optional, Boolean) Specifies whether to wait for all excluded nodes to be
removed from the cluster before clearing the voting configuration exclusions
list. Defaults to
true, meaning that all excluded nodes must be removed from the cluster before this API takes any action. If set to
falsethen the voting configuration exclusions list is cleared even if some excluded nodes are still in the cluster.
