Julian Hyde commented on OPTIQ-413:
-----------------------------------
Adding interface RelDataTypeSystem. The constructor of RelDataTypeFactoryImpl
now takes a RelDataTypeSystem. Most applications will use
RelDataTypeSystem.DEFAULT if you like.
Also adding a new connection property, "typeSystem", and adding a method
FrameworkConfig.getTypeSystem().
> Add RelDataTypeSystem plugin, allowing different max precision of a DECIMAL
> ---------------------------------------------------------------------------

>
> Hive has different max scale/precision than Optiq.
> This patch just changes it to Hive values.
> This is most probably not how to address this. May be we need some setter
> methods or factory for this.
> This patch is just to capture the type issues surrounding precision/scale in
> Optiq w.r.t Hive.
