=== Total Shards Per Node
|
||
|
|
|
||
|
|
The cluster-level shard allocator tries to spread the shards of a single index
|
||
|
|
across as many nodes as possible. However, depending on how many shards and
|
||
|
|
indices you have, and how big they are, it may not always be possible to spread
|
||
|
|
shards evenly.
|
||
|
|
|
||
|
|
The following _dynamic_ setting allows you to specify a hard limit on the total
|
||
|
|
number of shards from a single index allowed per node:
|
||
|
|
|
||
|
|
`index.routing.allocation.total_shards_per_node`::
|
||
|
|
|
||
|
|
The maximum number of shards (replicas and primaries) that will be
|
||
|
|
allocated to a single node. Defaults to unbounded.
|
||
|
|
|
||
|
|
[WARNING]
|
||
|
|
=======================================
|
||
|
|
This setting imposes a hard limit which can result in some shards not
|
||
|
|
being allocated.
|
||
|
|
|
||
|
|
Use with caution.
