Hello dialect experts,

what would be the best approach for creating a SqlAlchemy dialect for a new 
database system? 
Are there any recipes available for this area, or is the way to go to read 
code of existing dialects and derive my own dialect from those?

I had a first glance at some built-in dialects, and also some in external 
packages ... it is not always obvious to me why certain classes and methods 
have been implemented.
The obvious thing is to create a subclass of 
sqlalchemy.enginedefault.DefaultDialect, but how would I know which methods 
and class attributes to override/implement, except for going through the 
trial and error approach?
And then there are other classes which are implemented in some dialects, 
like compiler.DDLCompiler, compiler.GenericTypeCompiler, and so on ... 
where and how would I start best?

Any help would be very much appreciated.

Ciao ciao

Ralph
