Teradata recommends users to follow these steps to optimize performance when using the Aster R runner functions.

These steps create and mount the directory home/extensibility/stream on Aster cluster. During an Aster R session, virtual object files created using the R runner functions are saved in this directory. When the Aster R session ends, these objects are deleted.

For more information on Aster R runner functions and Aster virtual objects, see Using Aster R Runner Functions to Run R Functions in the Aster Database.

Run the following commands on the queen node.
  1. ncli node runonother "mkdir /data/stream"
