#Installation

Alauda Data Services Analytical Database E1 is delivered as an OLM operator package. Installing it is two separate steps: install the operator, then create a database cluster as a custom resource.

#Prerequisites

• An Alauda Container Platform cluster with OLM available, and permission to create a Subscription in the operators namespace.
• A default StorageClass, or a named StorageClass you will reference from the cluster manifest. Each replica claims at least one persistent volume for data, and a second one if you enable log persistence.
• A ZooKeeper™ ensemble reachable from the cluster namespace, required for replicated tables. Use three nodes or more. A cluster with replication configured but no reachable ensemble will start and then fail to replicate.
• Sufficient quota for the topology you intend to create: one pod and one data volume per replica, so a two-shard, two-replica cluster is four pods.
