Unfreeze index APIedit
Deprecated in 7.14
In 8.0, we removed the ability to freeze an index. In previous versions, freezing an index reduced its memory overhead. However, frozen indices are no longer useful due to recent improvements in heap memory usage. You can use this API to unfreeze indices that were frozen in 7.x. Frozen indices are not related to the frozen data tier.
