Can a UDx communicate back to the DB?
Posted: Tue Oct 13, 2015 8:00 pm
Hi guys,
Do you guys know if a UDx (either written in C++, R or Java) can communicate back to Vertica? That is, can the UDx itself connect back to the DB (i.e. using ODBC or JDVC) and get query the DB?
I found in the documentation where it says “The external procedure cannot communicate back to HP Vertica.” in the “Using External Procedures” section of the “Extending HP Vertica” document, but I can’t find any indication that a UDx cannot.
Thank you
