Properties

crate

bootstrap

mlockall

Set this property to true to lock the memory (Crate performs poorly when JVM starts swapping: you should ensure that it never swaps)

cluster

graceful_stop
force

The force setting allows you to force a shutdown of a node when the graceful shutdown process runs into the cluster.graceful_stop.timeout

min_availability

The minimum data availability the cluster needs to ensure when a certain node is shut down

reallocate

The cluster may reallocate shards to ensure minimum data availabillity before a certain node shuts down

timeout

The time to wait for the reallocation process to be finished

Defines how often the cluster collection metadata information if no concrete event is triggered

crate

Allow to control when rebalancing will happen based on the total state of all the indices shards in the cluster

balance
index

Defines a factor to the number of shards per index allocated on a specific node (float)

Defines a weight factor for the number of primaries of a specific index allocated on a node (float)

shard

Defines the weight factor for shards allocated on a node (float)

threshold

Minimal optimization value of operations that should be performed (non negative float)

cluster_concurrent_rebalance

Define how many concurrent rebalancing tasks are allowed cluster wide

disk
threshold_enabled

Prevent shard allocation on nodes depending on the disk usage

high

Defines the higher disk threshold limit for shard allocations

low

Defines the lower disk threshold limit for shard allocations

enable

Limit shard allocations to certain kinds of shards, for example if you perform a rolling cluster upgrade
