  • Ease of Use
    • Statistics (Monitoring Kamanja) Expanded - input/output adapters and storage adapters are now reporting relevant statistics.
    • FailedEvents Adapter Added - if configured, any messages that Kamanja manager fails to process are sent to this adapter along with a reason for its failure.
  • Adapters
    • Kafka Output Adapter Improved - send mechanism re-written to leverage new Kafka API.
  • Migration
    • Migration Implemented - migration tool created to support migration from Kamanja 1.1.x to 1.3.0 and from Kamanja 1.2.x to 1.3.0 (migration tool). For 1.1.x to 1.3.0 migration, Java/Scala model migration is not supported due to major interface changes. These must be updated for the new interfaces and manually re-compiled. Also not supported yet are custom types and custom JAR files.
    • Kafka API referenced instead of
    • Code-base now compiled in Scala 2.11.7 instead of 2.10.4.
