-------------------------------------
Summary: Iceberg query create inconsistent scan ranges between
consecutive runs
Key: IMPALA-10914
URL: https://issues.apache.org/jira/browse/IMPALA-10914
Project: IMPALA
Issue Type: Bug
Components: Distributed Exec
Affects Versions: Impala 4.0.0
Reporter: Riza Suminto
Assignee: Zoltán Borók-Nagy
When running a same query several times against hive table, scan ranges
assignment between query runs are identical. This helps towards efficiently
hitting already cached file handles and data.
However, for iceberg table query, consecutive runs of the same query yield
varying scan range assignment. This lead to more cache miss and slower scans.
