[role="xpack"] [[ilm-set-priority]] === Set priority Phases allowed: hot, warm, cold, frozen. Sets the <> of the index as soon as the policy enters the hot, warm, or cold phase. Higher priority indices are recovered before indices with lower priorities following a node restart. Generally, indexes in the hot phase should have the highest value and indexes in the cold phase should have the lowest values. For example: 100 for the hot phase, 50 for the warm phase, and 0 for the cold phase. Indices that don't set this value have a default priority of 1. [[ilm-set-priority-options]] ==== Options `priority`:: (Required, integer) The priority for the index. Must be 0 or greater. Set to `null` to remove the priority.
