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.
- ncli node runonother "mkdir /data/stream"
- ncli node runonother "chown -R extensibility:extensibility /data/stream"
- ncli node runonother "mkdir /home/extensibility/stream"
- ncli node runonother "chown -R extensibility:extensibility /home/extensibility/stream"
- ncli node runonother "mount --bind /data/stream /home/extensibility/stream"
