Zoltán Borók-Nagy updated IMPALA-12569:
---------------------------------------
Priority: Critical (was: Major)
> Harden long string testing
> --------------------------
>
> Key: IMPALA-12569
> URL: https://issues.apache.org/jira/browse/IMPALA-12569
> Project: IMPALA
> Issue Type: Sub-task
> Components: Backend, Infrastructure
> Reporter: Zoltán Borók-Nagy
> Priority: Critical
>
> With small string optimization [~csringhofer] pointed out that most of our
> test data have small strings. And new features are typically tested on the
> existing test tables (e.g. alltypes that only have small strings), or they
> add new tests with usually small strings only. The latter is hard to prevent.
> Therefore the long strings might have less test coverage if we don't pay
> enough attention.
> To make the situation better, we could
> # Add long string data to the string column of alltypes table and
> complextypestbl and update the tests
> # Add backend flag the makes StringValue.Smallify() a no-op, and create a
> test job (probably with an ASAN build) that runs the tests with that flag
> turned on.
