=== Cluster changes
|
|
|
|
==== `:` is no longer allowed in cluster name
|
|
|
|
Due to cross-cluster search using `:` to separate a cluster and index name,
|
|
cluster names may no longer contain `:`.
|
|
|
|
==== New default for `wait_for_active_shards` parameter of the open index command
|
|
|
|
The default value for the `wait_for_active_shards` parameter of the open index API
|
|
is changed from 0 to 1, which means that the command will now by default wait for all
|
|
primary shards of the opened index to be allocated.
|
|
|
|
==== Shard preferences `_primary`, `_primary_first`, `_replica`, and `_replica_first` are removed
|
|
These shard preferences are removed in favour of the `_prefer_nodes` and `_only_nodes` preferences.
