 Review comment:
   Do you mean we should refactor getTable(String, String) to 
getTable(TableName)?
   We can try it, but it does mean an additional change of 80 usages.

> There are many places in which "{databasename}.{tablename}" is passed as a 
> single string; there are some places where the they travel as 2 separate 
> arguments.
> Idea would be to introduce a simple immutable class with 2 fields ; and pass 
> these informations together. Making this better is required if we would be 
> wanting to enable dot in tablenames
