Index recovery prioritization
editIndex recovery prioritization
editUnallocated shards are recovered in order of priority, whenever possible. Indices are sorted into priority order as follows:
-
the optional
index.priority
setting (higher before lower) - the index creation date (higher before lower)
- the index name (higher before lower)
This means that, by default, newer indices will be recovered before older indices.
Use the per-index dynamically updateable index.priority
setting to customise
the index prioritization order. For instance:
PUT index_1 PUT index_2 PUT index_3 { "settings": { "index.priority": 10 } } PUT index_4 { "settings": { "index.priority": 5 } }
In the above example:
-
index_3
will be recovered first because it has the highestindex.priority
. -
index_4
will be recovered next because it has the next highest priority. -
index_2
will be recovered next because it was created more recently. -
index_1
will be recovered last.
This setting accepts an integer, and can be updated on a live index with the update index settings API:
PUT index_4/_settings { "index.priority": 1 }
