(yes, it includes a fix for CALCITE-2109) against [latest
calcite-test-dataset|https://github.com/vlsi/calcite-test-dataset/commit/9aaa8e2eddd96073a18bd40011d785d8880594fc].
I ran {noformat}mvn -pl mongodb -Pit test integration-test{noformat} and I got
the following errors {noformat}Failed tests:

Are these 2 failures and 1 error expected? If they're OK then let's either
disable the tests or fix the expected output.
> Update Mongo driver version

> Key: CALCITE-1697
> URL: https://issues.apache.org/jira/browse/CALCITE-1697
> Project: Calcite
> Issue Type: Improvement
> Components: mongodb
> Affects Versions: 1.11.0
> Reporter: Michael Mior
> Assignee: Michael Mior
> Fix For: 1.16.0
>
>
> The current version of the Mongo driver is quite outdated. This causes issues
> such as getCollectionNames returning empty on newer versions of the Mongo
> server. This effectively makes the driver unusable since Calcite will never
> see any tables in the schema.
