Number of Arguments in R Scalar Function

vioravis

Vertica 7.0 Programmer's Guide has the following note:

Note: : Transform functions written in R can have an unlimited number of arguments. Scalar functions written in R are limited to a maximum number of 32 arguments.

Is there still a limit of 32 arguments (columns) to a Scalar function? If so, could someone explain why is it so? Is there a way to pass more than 32 columns to a R Scalar function?

Thank you.

Hi Ravi,

For Vertica 7.1.x, the limit is now 500 arguments. We will update the documentation to reflect this new limit.

Sorry for the documentation error!

Thanks Chris. Is the updated limit of 500 available only from 7.1 or is it available in 7.0 as well?

Hi Ravi, sorry, I just confirmed. It is only available in 7.1.
