Mihai Budiu commented on CALCITE-7742:
--------------------------------------

These numbers amount to zero.

You have 45 days to work on something? Our most constrained resources is code 
review capacity. You can pick up and review recent PRs. Each should take you 
much less.

I am not sure what "project-style capacity" means.

> Test framework has non-determinstic tests

>                 URL: https://issues.apache.org/jira/browse/CALCITE-7742
>             Project: Calcite
>          Issue Type: Bug
>          Components: core
>    Affects Versions: 1.42.0
>            Reporter: Mihai Budiu
>            Priority: Minor
>
> Some tests intermittently fail in CI, here's an example output:
> {code:java}
> FAILURE   0.1sec, 
> org.apache.calcite.rel.rel2sql.RelToSqlConverterRoundTripTest > 
> testCastToChar()
>     java.lang.AssertionError:
>     Expected: is "SELECT CAST(`product_id` AS CHAR)\nFROM 
> `foodmart`.`product`"
>          but: was "SELECT CAST(`product_id` AS CHAR(1))\nFROM 
> `foodmart`.`product`" {code}
> Seemingly this is because there is some shared state between concurrent 
> tests, e.g., perhaps a custom type system installed?
