=== Frozen shards decider
|
|
|
|
The frozen shards decider (`frozen_shards`) calculates the memory required to search
|
|
the current set of partially mounted indices in the frozen tier. Based on a
|
|
required memory amount per shard, it calculates the necessary memory in the frozen tier.

==== Configuration settings
|
|
|
|
`memory_per_shard`::
|
|
(Optional, <<byte-units,byte value>>)
|
|
The memory needed per shard, in bytes. Defaults to 2000 shards per 64 GB node (roughly 32 MB per shard).
|
|
Notice that this is total memory, not heap, assuming that the Elasticsearch default heap sizing
|
|
mechanism is used and that nodes are not bigger than 64 GB.
