Re: thread_cache_size and buffer pool


Hi Federico.

It is documented, in the threadpool document https://mariadb.com/kb/en/mariadb/documentation/optimization-and-tuning/buffers-caches-and-threads/thread-pool/threadpool-in-55/

It says ​following, towards the end of the ​doc, in “Notes” 
The thread_cache_size system variable is not used when the thread pool is used and the Threads_cached status variable will have a value of 0.

Hi all

Would someone kindly explain (or document) how @@thread_cache_size affects the pool-of-threads? Do values > 0 make sense?
