Freezeedit

Phases allowed: cold.

Freezes an index to minimize its memory footprint.

Freezing an index closes the index and reopens it within the same API call. This means that for a short time no primaries are allocated. The cluster will go red until the primaries are allocated. This limitation might be removed in the future.

Optionsedit

None.
