Investigate ways of persisting policy state information with different structures at run time. One approach could be to use Avro & Apache Hive. [There is also a NoSQL/JSON option available in MariaDB and Postgres]

Another option is the Apache Cassandra database. Datastax provide a Java Driver for Apache Cassandra.

Writing plugins towards state information stored in CPS might be another approach that could work across all the PDPs.

References to DB should be moved from persistence.xml to properties file to facilitate the use of alternate databases.

We can modify the current code to read in the location of a properties file

-Djdbc.properties=/path/to/jdbc.properties
 String propertiesPath = System.getProperty( "jdbc.properties" );

if ( propertiesPath != null )
{
     FileInputStream in = new FileInputStream( propertiesPath );

     try
     {
         jdbcProperties = Properties.load( in );
     }
     finally
     {

Kubernetes

There are four different ways that you can use a ConfigMap to configure a container inside a Pod:

  • Inside a container command and args
  • Environment variables for a container
  • Add a file in read-only volume, for the application to read
  • Write code to run inside the Pod that uses the Kubernetes API to read a ConfigMap

Currently, the models Provider classes manage transactions. Transaction management should be moved to client for better performance and atomicity. This will also eliminate the need for caching on the client side.

Note: The transactional annotation can be used  to group transactions together.

Ideally transactions should be executed serially in order to avoid dirty reads, non-repeatable reads and phantom reads. 

Note: DatabasePolicyModelsProviderImpl in the models-provider package provides rest APIs such as createServiceTemplate, updateServiceTemplate and deleteServiceTemplate which in turn call the corresponding APIs from AuthorativeToscaProvider in the models-tosca package..

How best to deal with CRUD of data types in policy-api and policy-models. It is possible only to create data types indirectly in policy type create requests. Update and delete of data types is not possible.

SimpleToscaProvider contains the following methods not available in AuthorativeToscaProvider : getDataTypes, getCascadedDataTypes, createDataTypes, updateDataTypes and deleteDataType.

Investigate what's involved in switching to spring
StoryLiam Fallon4

Externalizing ONAP DBs to a separate namespace

We would like to improve the current situation by implementing a two staged deployment:

1) Deploy all required DB engines (can be done using community charts or any user chart)

2) Deploy ONAP components & configure them to make use of those engines


This would allow use to basically bring his own database for ONAP no matter if it is running in the same k8s cluster or it has been provided by some DBaaS solution. Additionally it makes our deployment more modular and configurable thus may result in significant footprint savings.
