This is a good point. On the one hand, I do agree that the API for simple things like processing CSV files shouldn't be overly complex. So perhaps we could start with a simple API and extend it later. On the other hand, understanding how some of the more complex cases ought to work provides insight into handling the simpler cases. So I think we should aim to have at least a sketch of a design for the whole feature, and then if in phase 1 we want to implement only the easier parts, that's OK.
Right. In any case, I should clearify what this API could cover by this patch and what could not. # And also how far I and my collaborator can implement.. As Itagaki points out, we have two types of FDW implementations in progress: flat file wrapper and postgresql wrapper. these items are described in wiki: http://wiki.postgresql.org/wiki/SQL/MED But it may be hard to get what this fdw routines 'could' provide, so I and my collaborator is now summarizing these items to discuss and ask for help. Anyway I think these items are needed to discuss further. - API design that is used in executor for a single external table. - simple FDW implements to clearfy what this API could provide. These items will be shown by my collaborator soon. thanks in advance, SAKAMOTO Masahiko NIPPON TELEGRAPH AND TELEPHONE CORPORATION NTT Open Source Software Center e-mail: sakamoto.masah...@oss.ntt.co.jp -- Sent via pgsql-hackers mailing list (pgsql-hackers@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
