-----------------------------------
Summary: DRS-level scan optimization leads to failed scans
Key: KUDU-3384
URL: https://issues.apache.org/jira/browse/KUDU-3384
Project: Kudu
Issue Type: Bug
Components: tserver
Affects Versions: 1.17.0
Reporter: Alexey Serbin
Recently, a new DRS-level optimization for scan operations has been introduced
with changelist
[936d7edc4|https://github.com/apache/kudu/commit/936d7edc4e4b69d2e1f1dffc96760cb3fd57a934].
The newly introduced DRS-level optimization leads to scan failures when all of
the following turns true:
* all the primary key columns are of integer types
* the table has no hash partitioning
* the table contains a value with all primary key columns set to INT{x}_MAX
correspondingly
* the scan request is to scan all the table's data
I suspect that some of the conditions above might be relaxed, but I have a test
case that reproduces the issue as described.
