[jira] [Created] (IMPALA-7543) Enhance scan ranges to support
sub-ranges
Zoltán Borók-Nagy created IMPALA-7543:
-----------------------------------------
Summary: Enhance scan ranges to support sub-ranges
Key: IMPALA-7543
URL: https://issues.apache.org/jira/browse/IMPALA-7543
Project: IMPALA
Issue Type: Sub-task
Reporter: Zoltán Borók-Nagy
For IMPALA-5843 we need to have smarter scan ranges that only read a list of inner ranges.
It'll be useful for Parquet files that have page index, so Impala will only read the relevant pages.
