Hi,
We have created R UDFs in Vertica 6.1 and would like to know whether these UDFs are compatible with Vertica 7.0.0 (Crane).
In the community edition of Vertica 7.0.0 downloads page, I see "User Defined Functions in R: sources package" which was not part of 6.1.
Has something changed between 6.1 and 7.0 in terms of creating and using R UDFs? Could someone please clarify.
Thank you.

R UDF Compatibility in Vertica 7

+2Hi Ravi,
R UDF's written for Vertica 6.1 should be compatible with Vertica 7 as well.
To use R in Vertica 7, you need to install the R Language Pack for your platform. This is the same as in 6.1.
It is also possible to build the R connector from source code, rather than from the pre-compiled binary package. That's what the "source packages" download is that you're referring to. It's how Vertica's R functionality was installed prior to 6.1. Most users will not want to install R this way today.
We provide the source in part because we have to -- the R interpreter is licensed under the GPL; we modify it (to run from within Vertica), so we're expected to publish our code as well. (The package was actually part of 6.1 as well. But I think it was on a different part of the page; people often didn't see it.) We also publish it because, while it would take a lot of effort to modify this code, you could in principle take it and do something really cool with it, like run Python or some totally-different language. No one's done this yet, but I have my fingers crossed :-)
