Autoscaling deciders

Reactive storage decider

Estimates required storage capacity of current data set. Available for policies governing data nodes.

Proactive storage decider

Estimates required storage capacity based on current ingestion into hot nodes. Available for policies governing hot data nodes.

Frozen shards decider

Estimates required memory capacity based on the number of partially mounted shards. Available for policies governing frozen data nodes.

Frozen storage decider

Estimates required storage capacity as a percentage of the total data set of partially mounted indices. Available for policies governing frozen data nodes.

Frozen existence decider

Estimates a minimum require frozen memory and storage capacity when any index is in the frozen ILM phase.

Machine learning decider

Estimates required memory capacity based on machine learning jobs. Available for policies governing machine learning nodes.

Fixed decider

Responds with a fixed required capacity. This decider is intended for testing only.
