Impala pod configuration option in CDW Private Cloud
Cloudera Data Warehouse (CDW) allocates standard resources to the warehouses that are suitable for most workloads. You can control the size of the Virtual Warehouse at the time of creation by choosing the number of nodes to be used. You can either select a default option or a custom option that you may have created.
What custom pod configuration is in CDW
Pod config is a drop-down menu that you see when you are creating an
Impala Virtual Warehouse. It displays a default
Cdw defaults option and any custom pod
configurations that you may have created for Impala.
By using custom pod configurations, you can also change the resources used by the critical Impala components, such as the coordinators, executors, and catalog daemons to pack a particular number of pods into a Kubernetes node or to create extra-large daemons to handle specific workloads.
