Start only whats needed and Spring Configuration Integration

Start Clients only when needed

Astra offers a wide variety of Apis and functions. (see Architecture for details of ports). Previous the SDK initialized all connections for you as long as you provided enough parameters. This behavior leads to. usage of resources not in used and port openings that are not really used.

With the builders you would have to enable functions explicitely:

AstraClient.builder()
           .enableCql()
           .enableGrpc()
           .enableDownloadSecureConnectBundle()

With the Spring configuration file you would have to also enable

astra:
  api:
    application-token: "AstraCS:mytoken..."
    database-region: eu-west-1
    grpc:
      enabled: true
...

Merge and fined grained configuration of the driver with Spring config

Java Driver used to read application.conf configuration file to load fine grained settings. You can all define any driver key in astra.cql.driver-config.

Here is a sample:

astra:
  api:
    application-token: change_me
    database-id: change_me
    database-region: change_me
    grpc:
      enabled: true
  cql:
    enabled: true
    download-scb: 
      enabled: true
    metrics:
      enabled: false
    driver-config:
      basic:
        request:
          timeout: 5s
          consistency: LOCAL_QUORUM
          page-size: 5000
        session-keyspace: feeds_reader
      advanced:
        connection:
          init-query-timeout: 5s      
          set-keyspace-timeout: 5s
        control-connection.timeout: 5s

Release of constraint on DatabaseTierType

The devops API database will retrieve the tier type of your instances. With multiple updates over the months we changed from an enum to a String.
