Dataproc Metastore scaling factors

When you create a Dataproc Metastore service, you can choose to use a Dataproc Metastore 2 service or a Dataproc Metastore 1 service.

This document explains how to control resource consumption for Dataproc Metastore 2.

Scaling factors and editions

Dataproc Metastore 2 uses scaling factors and editions (workloads) to handle varying levels of stability and workloads. You select your scaling factor and edition when you create a Dataproc Metastore service.

After you create your Dataproc Metastore service, you can scale the service up or down by modifying the scaling factor. Scaling factors range from small to XLarge and are represented by a number ranging from 0.1 to 6.0.

For more information about editions and scaling factors, see Scaling factors and workloads.


Dataproc Metastore 2 also supports autoscaling. If you turn on autoscaling, you set a minimum scaling factor and a maximum scaling factor. After these parameters are set, your service automatically increases or decreases resource consumption to run workloads. Autoscaling is only available for single region Dataproc Metastore instances.

For more information on setting up autoscaling, see Create an autoscaling service.
