Ye Zihao created IMPALA-12544:
---------------------------------
Summary: Replace scan progress with query progress as progress
reporting for the shell
Key: IMPALA-12544
URL: https://issues.apache.org/jira/browse/IMPALA-12544
Project: IMPALA
Issue Type: Improvement
Components: Clients
Affects Versions: Impala 4.3.0
Reporter: Ye Zihao
Assignee: Ye Zihao
After IMPALA-12048 is resolved, we can see the query progress of a query on the
/queries page. Unlike scan progress, it uses the completion count of query
fragment instances to calculate progress, providing a more accurate reflection
of query execution progress, especially for computation-intensive queries (such
as TPC-DS query 78). Perhaps we should also use query progress instead of scan
progress in the dynamic progress reporting for the impala shell, to provide
more accurate query completion progress reports and avoid cases where the scan
is complete but the query still needs a long time to finish computation even
though the progress is reported as 100%.
