We've gotten nowhere on this despite trying. Installing GO on windows went fine, based on what Ian suggested, but specifying GOOS=nsx fails immediately as being unrecognized (rather obvious). The archictture is not a powerPC, so I'm not sure why I would start there - it is a big-endian x86. On

errgroup does not terminate. But will signal the (sub)context returned by WithContext when any goroutine returns with an error. So if your functions handle the context cancelation by exiting, then you can cancel other goroutines. I asvice using such sub context with requests, too. -- You rece

Behind the scenes, DB is actually a connection pool, not a single connection, which will open new connections when you need them. In our services - which do a LOT of DB work, we only open a single sql.DB connection and share it among all our handlers. Whenever a handler does a db.Whatever, the db

Thanks Ian, no need to apologize, I know this stuff is hard. I'll adjust my approach and see if I can conjure up enough working C code to try buffering the incoming data, and then call into Go in batches. Even buffering as few as 10 records at a time should significantly speed up the executio
