PNDA 5.0

Code name: Mammoth Drop Bear

PNDA 5.0 is a major release containing many improvement related to the deployment.

Ubuntu

Ubuntu is not supported any longer. We're now focusing on RedHat-like Linux distributions.

Perimeter security for user services

PNDA and Hadoop components are now secured behind the Knox Application Gateway, and many components have been modified to support configurable authorization.

Deployable to VMWare

PNDA is now deployable on VMWare with Terraform. It must still be considered as experimental feature as it as not been extensively tested.

Name based node/service resolution

PNDA now heavily uses Consul as part of its service discovery mechanism. It opens up a lot of new possibilities that will be part of next releases.

Revised ingest mechanics (API changes)

As part of PDP-2 Gobblin can now ingest data in protobuf and other formats. It is no longer necessary to apply an avro envelope to data.

Apache Flink integration

As part of PDP-3, Flink can now be used as an alternative to Spark. It allows for stream processing at event level granularity and/or very low latency with more advanced windowing and other stream processing features that Spark doesn't currently offer.

ONAP

PNDA will be part of the next ONAP release (Code name: Casablanca). Hence some improvements have been made related to the mirror creation. It can now be built to a Docker container. As PNDA for ONAP primary deployment target is Openstack a few updates have also been made to the Heat templates and the pnda-cli.
