-----------------------------------------
Summary: Too much threads started on empty cluster
Key: IGNITE-18902
URL: https://issues.apache.org/jira/browse/IGNITE-18902
Project: Ignite
Issue Type: Improvement
Reporter: Konstantin Orlov
Attachments: after_start.txt, after_table_creation.txt
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.
