We're pushing a lot of data in the form of bulk indexing requests and saturating the available thread pools. Can you point me to a good article on optimally sizing ES thread pools?

Thanks.

What are the issues in the cluster that lead you to the conclusion that you need to modify the threadpools? What is the size and specification of your cluster? What type of hardware are you using? How much data are you indexing per day? How many indices and shards are you actively indexing into?

May be this? [Tune for indexing speed | Elasticsearch Guide [8.11] | Elastic](https://www.elastic.co/guide/en/elasticsearch/reference/current/tune-for-indexing-speed.html)
