Hi, I'd like to return some scanner statistics from co-processor back to the client. E.g. number of rows filtered out. There isn't a way to add an arbitrary attributes to Result object, which would be simplest--e.g. I could do that in postScannerNext.
The only way I can think of, is to add special Result object--again in postScannerNext--to the result set. The Result object would carry the needed info as bytes and could be watched for and interpreted on the client side. Is it reasonable at all? Is it at all dangerous to do that in postScannerNext or in general? Would it interfere with some client or server-side logic? Any ideas are welcome! Thank you in advance, Alex Baranau
