Request handler for a function in R

Written by

A request handler is a function used to process each R function call. When creating a function version, you must specify the entry point, which consists of the file name and the name of the R function that receives the request (see example for the handler in the function.R or function.handler file).

Note

At any given time, a single function instance processes only one request.

The handler can accept and return various types of data. For more information about this and available ways to set a request handler, see this guide.
