> 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
> Priority: Major
> Labels: impala-iceberg
>
> 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.
