Hallo Herr Grimmer,
hier die ersten technischen Fragen (natürlich gleich in englisch):
1.) Cluster Management and SQL extensions
We would like to extend the SQL syntax for cluster management similar to the
syntax already being implemented for NDB online node adding. Unfortunately I
haven't found a syntax tree for the SQL syntax that will be used for this
purpose. Since the syntax should be very similar to the syntax used for DDE it
would be good if we could have a preliminary syntax tree version. Is there a
way to get to it?
2.) Extending the syntax of SQL
Additionally to the cluster management extensions of the SQL syntax, which we
would like to adapt from the NDB Cluster management, we will probably need
further extensions not included in the NDB extensions. Is there documentation
available that we can use with an easy "HOW TO" extend the SQL syntax?? We
would exactly need to know witch classes we need to deal with and what we need
to change or what we need to hack for our selves.
3.) Foreign keys implementation above the storage engines
My first question to this topic is...how far along is it? Has the handler.h
interface been changed yet? If yes what when will the internals documentation
be changed? Does this implementation only include the foreign keys or does it
also include unique constraints and/or range constrains or similar?
If there are any questions please don't hesitate to ask. Also if the answers
are a bit to long for eMails I'm always willing to talk in person!
Cheers,
Peter
