This topic describes steps you must take to configure the Cassandra database
component for an Apigee hybrid production installation.
Configure storage and heap settings
For a production installation of Apigee hybrid, Google recommends that you add the
following storage and heap settings to your overrides file and apply them to the cluster:
For the Cassandra database, hybrid runtime uses
dynamically created persistent volumes to store data. To configure
Cassandra properly for a production environment, you must configure a
StorageClass
definition that is backed by a solid-state drive (SSD) and make it the default
class. See StorageClass configuration for detailed steps.
