Aleksandr Efimov commented on IMPALA-15149:
-------------------------------------------
A patch is available for review: https://gerrit.cloudera.org/c/24595/
It adds type-aware verification for TRINO_QUERY results using PREPARE/DESCRIBE
OUTPUT metadata, including empty results and non-finite FLOAT/DOUBLE values.
Validation: 35 focused tests passed in the Linux Impala environment; the wire
format was verified against Trino 482.
> Add type-aware result checking for Trino in .test files
