External database options
Review the following options to find out whether to use a built-in or other external database type.
When using an external database for cluster services and components, Cloudbreak supports selected built-in types and allows for specifying other types. Cloudbreak supports the following external database options:
|Built-in types||Cloudbreak includes a few built-in types: Hive, Druid, Ranger, Superset, and Oozie.||Use a standard blueprint which does not include any JDBC parameters. Cloudbreak automatically injects the JDBC property variables into the blueprint.||Simply register the database in the UI. After that, you can attach the database config to your clusters.||Refer to Example 1|
|Other types||In addition to the built-in types, Cloudbreak allows you to specify custom types. In the UI, this corresponds to the UI option is called “Other” > “Enter the type”.||You must provide a custom dynamic blueprint which includes RDBMS-specific variables. Refer to Creating a template blueprint.||Prepare your custom blueprint first. Next, register the database in the UI. After that, you can attach the database config to your clusters.||Refer to Example 2|
During cluster create, Cloudbreak checks whether the JDBC properties are present in the blueprint:
