I was wondering if its possible for the C API (or Java c interface) to update a file on disk with k objects (similar to how a tickerplant updates the tick log)
Basically want to implement journaling mechanism, if the feed handler drops a message from its queue and the ticker plant never receives the message - replaying the kdb tick log won’t recover the data. (Of course the feed handler could log in plane text, but I’m trying to see if I can avoid reading/parsing a csv file)
From what I can tell the khpun function can only open a handle to a q process, not a file handle like hopen
So, is there an out of the box implementation for c/java API to update a binary file and then a q process read/process the file with -11!
Or so we need to write a custom deserializer to read the binary file?
