----------------------------------------

             Summary: Leaking H2 internals when querying from pyignite
                 Key: IGNITE-12840
                 URL: https://issues.apache.org/jira/browse/IGNITE-12840
             Project: Ignite
          Issue Type: Bug
          Components: clients, python
    Affects Versions: 2.8
            Reporter: Ilya Kasnacheev
             Fix For: 2.8.1


I am sharing a slightly modified reproducer from userlist.

To run:

Start a node (with JVM_OPTS=-Xmx512m to see it most clearly).
Run a .sql file with sqlline (!run)
python3 test_insert_in_cache.py
in parallel terminal: python3 read_cache_insert_update_table.py

Then you should observe slowing down and long GC pauses on server node. jmap will collect ever-increasing heap dumps.
