My project using elastic cloud but reject error: EsThreadPoolExecutor[name = instance-0000000003/write, queue capacity = 200 On breaking change description "Thread pool settings are now node-level settings. As such, it is not possible to update thread pool settings via the cluster settings API." link here: [https://www.elastic.co/guide/en/elasticsearch/reference/5.1/breaking\_50\_settings\_changes.html#\_forbid\_changing\_of\_thread\_pool\_types](https://www.elastic.co/guide/en/elasticsearch/reference/5.1/breaking_50_settings_changes.html#_forbid_changing_of_thread_pool_types) So, how to setting queue size on my elastic cloud? Thanks. ---

What is the full error you are seeing? Why do you think you need to change this setting? Are you by any chance indexing into a large number of indices and shards concurrently and as a result suffer from [this](https://www.elastic.co/blog/why-am-i-seeing-bulk-rejections-in-my-elasticsearch-cluster)? ---

Hi Christian, Thanks for reply. This is full error: { "error": { "root\_cause": [ { "type": "es\_rejected\_execution\_exception", "reason": "rejected execution of processing of [193927725][indices:data/write/update[s]]: update {[comments][\_doc][...], doc\_as\_upsert[true], doc[index {[null][\_doc][null], source[...]}], scripted\_upsert[false], detect\_noop[true]} on EsThreadPoolExecutor[name = instance-0000000003/write, queue capacity = 200, org.elasticsearch.common.util.concurrent.EsThreadPoolExecutor@788f8d44[Running, pool size = 16, active threads = 16, queued tasks = 200, completed tasks = 70440089]]" } ], "type": "es\_rejected\_execution\_exception", "reason": "rejected execution of processing of [193927725][indices:data/write/update[s]]: update {[comments][\_doc][...], doc\_as\_upsert[true], doc[index {[null][\_doc][null], source[...]}], scripted\_upsert[false], detect\_noop[true]} on EsThreadPoolExecutor[name = instance-0000000003/write, queue capacity = 200, org.elasticsearch.common.util.concurrent.EsThreadPoolExecutor@788f8d44[Running, pool size = 16, active threads = 16, queued tasks = 200, completed tasks = 70440089]]" }, "status": 429 } My app listens to data from Facebook, therefore depends on traffic from Facebook.

How many indices and shards are you actively indexing into? What is the size of your bulk requests? ---

This is the current my system info: Nodes: 2 Indices: 66 Primary Shards: 150 Documents: 497m App reveive data from FB and write by API /\_updates, not using bulk request. ---

How many concurrent clients/threads do you have adding or modifying data in Elasticsearch? Note that updating or indexing documents individually rather than in bulk will add a lot of overhead and result in lower performance compared to using bulk requests. ---
