Nick Dimiduk commented on CALCITE-522:
--------------------------------------
bq. Fine to deprecate methods, but you need to provide a comment when they will
be removed. Generally '// will be removed before 2.0'. In this case, since
Avatica is still experimental, I think you can just remove them. But just
mention that they've been removed in the commit comment.
I don't think we make any promises about RPC API stability yet. I think we
should focus on improvements (breaking if necessary) until we have a very broad
feature coverage. Maybe the Calcite-2.0 release can define some stable RPC API
for rolling upgrades and external projects to depend upon. This means that any
non-Java clients should be included in Calcite for now so that they can be
tested along with the rest of the release.

>
> A lot of DatabaseMetaData methods are not parameterized, and give the same
> answer every time. Some examples:
> * allProceduresAreCallable
> * getUserName
> * isReadOnly
> * getDatabaseProductName
> * getDatabaseProductVersion
> * getDriverName
> * getDriverVersion
> * getDriverMajorVersion
> * getDriverMinorVersion
> * getSqlKeywords
> * getNumericFunctions
> * getStringFunctions
> * getSystemFunctions
> * getTimeDateFunctions
> This task would define an enum of properties, add a method to Meta that
> returns (property, value) map.
> See DatabaseMetaData and Connection for the full list.
> Obsolete the following Meta methods:
> * getSqlKeywords
> * getNumericFunctions
> * getStringFunctions
> * getSystemFunctions
> * getTimeDateFunctions
