Yandex Data Processing host classes

The host class determines the computing power allocated for each host in a cluster. When you change the host class for a cluster, all existing hosts change accordingly.

The available storage size does not depend on the host class. For storage limitations, see Quotas and limits.

Hosts in Yandex Data Processing clusters are deployed on Yandex Compute Cloud VMs. You can create these VMs on any platforms Compute Cloud supports. To learn more about the platforms, see Platforms.

A suitable host class depends on driver deploy mode:

• In deployMode=cluster mode, when the driver runs on one of the cluster's compute hosts, a subcluster with the master host requires 4–8 CPU cores and 16 GB of RAM.
• In deployMode=client mode, when the driver run on the cluster's master host, the compute capacity depends on the job logic and the number of concurrent jobs.

For more information on driver deploy modes and computing resource usage, see Resource allocation.

The full list of possible host configurations on each platform is provided below.
