> Seems we start unreasonable amount of threads. Thread dump right after the start of a single node shows a 170 threads with prefix <node_name> ('idt_n_0' in dumps), 157 of them belongs to the JRaft. Creation of a table contributes another 160 threads to the dump (330 in total), and 114 of them belongs to the JRaft (271 in total).
> Let's investigate if we really need all those threads or we can do better. You could find thread dumps attached below.
