[jira] [Created] (IMPALA-11868) Annotate the Java thread name with query_id during planning
Joe McDonnell created IMPALA-11868:
--------------------------------------
Summary: Annotate the Java thread name with query_id during planning
Key: IMPALA-11868
URL: https://issues.apache.org/jira/browse/IMPALA-11868
Project: IMPALA
Issue Type: Improvement
Components: Frontend
Affects Versions: Impala 4.3.0
Reporter: Joe McDonnell
Some pieces of catalog code have been using the ThreadNameAnnotator to modify the Java thread name at runtime. This greatly improves the information available via jstacks. For example:
{noformat}
"Thread-543 [invalidating metadata - 579/647 dbs complete]" #1447 prio=5 os_prio=0 tid=0x0000000010f57800 nid=0x75fd runnable [0x00007fe4d265f000]{noformat}
We should do something similar for queries that call into Java frontend code (e.g. during planning). It would be useful to know the query_id for threads when looking at a jstack output.
The main priority would be locations where a thread could spend significant time or get blocked. The most obvious example is during planning:
