Mihai Budiu commented on CALCITE-7227:
--------------------------------------
That's what we did: we produced another implementation, but ended up copying
most of the rules; sometimes removing rules breaks things, so we erred on the
safe side and kept the tested implementations until we have time to review them.
> There is no way to modify the StandardConvertletTable

> Key: CALCITE-7227
> URL: https://issues.apache.org/jira/browse/CALCITE-7227
> Project: Calcite
> Issue Type: Wish
> Components: core
> Affects Versions: 1.40.0
> Reporter: Mihai Budiu
> Priority: Minor
>
> The convertlet table has a lot of functionality, but there is no easy way to,
> let's say, exclude one of the conversions that is undesirable. Copying and
> modifying the whole class is a solution, but it is not great. Adding new
> conversions seems possible, but excluding the existing ones seems impossible.
