I'm wanting to find out why there are a large number of primary shards for profiling indices and if I can reduce the number of shards or remove the indices entirely given we are not using profiling?
We're on Elastic Cloud 8.15.2.
These are the settings for the .profiling-symbols-private-v001 index showing that number_of_replicas is 16.
