What is thread in MySQL?

Is MySQL single threaded?

MySQL is fully multithreaded, and makes use of all CPUs made available to it. Not all CPUs may be available; modern operating systems should be able to utilize all underlying CPUs, but also make it possible to restrict a process to a specific CPU or sets of CPUs.

How many threads can MySQL handle?

The maximum number of threads per group is 4096 (or 4095 on some systems where one thread is used internally). The thread pool separates connections and threads, so there is no fixed relationship between connections and the threads that execute statements received from those connections.

How do I see what MySQL threads are running?

The 'SHOW processlist' command can be used to display the running thread related to only your MySQL account. We can see almost all running threads if we have process privileges. It shows which threads are running.

How do I find MySQL thread ID?

SELECT * FROM INFORMATION_SCHEMA. PROCESSLIST WHERE STATE = "executing"; It contains a column Id which is the Id number of all the threads currently running.
