[3.6.0] - 2025-10-10​

Rasa Pro Services 3.6.0 (2025-10-10)

Features​

  • Add support for IAM authentication for AWS RDS database in the analytics service. To enable this feature, set the following environment variables:

    • IAM_CLOUD_PROVIDER: set to aws to enable IAM authentication for AWS RDS
    • RASA_ANALYTICS_DB_HOST_NAME: <your-db-hostname> the hostname of the RDS instance
    • RASA_ANALYTICS_DB_PORT: <your-db-port> the port of the RDS instance
    • RASA_ANALYTICS_DB_NAME: <your-db-name> the name of the database
    • RASA_ANALYTICS_DB_USERNAME: <your-db-username> the username to connect to the database
    • AWS_DEFAULT_REGION: <your-aws-region> the AWS region where the RDS instance is hosted

    Additionally, you can also set the following optional environment variables:

    • RASA_ANALYTICS_DB_SSL_MODE: the SSL mode to use when connecting to the database, e.g. verify-full or verify-ca
    • RASA_ANALYTICS_DB_SSL_CA_LOCATION: the path to the SSL root certificate to use when connecting to the database

    When these environment variables are set, the analytics service will use IAM authentication to connect to the AWS RDS database.

  • Add support for IAM authentication for AWS Managed Streaming for Apache Kafka in the analytics service. To enable this feature, set the following environment variables:

    • IAM_CLOUD_PROVIDER: set to aws to enable IAM authentication for AWS MSK
    • AWS_DEFAULT_REGION: <your-aws-region> the AWS region where the MSK instance is hosted
    • KAFKA_SECURITY_PROTOCOL: set to SASL_SSL to use SASL over SSL
    • KAFKA_SASL_MECHANISM: set to OAUTHBEARER to use OAuth Bearer token authentication
    • KAFKA_SSL_CA_LOCATION: the path to the SSL root certificate to use when connecting to the MSK cluster, this can be downloaded from Amazon Trust Services.

    When these environment variables are set, the analytics service will use IAM authentication to generate temporary credentials to connect to AWS MSK.

  • Configure Analytics service to connect to Kafka broker using mTLS. To enable this feature, set the following environment variables:

    • KAFKA_SSL_CERTFILE_LOCATION: Path to the client certificate file.
    • KAFKA_SSL_KEYFILE_LOCATION: Path to the client private key file.

Improvements​

  • Add new environment variables for each AWS service integration (RDS, MSK) that indicates whether to use IAM authentication when connecting to the service:
    • KAFKA_MSK_AWS_IAM_ENABLED - set to true to enable IAM authentication for MSK connections.
    • RDS_SQL_DB_AWS_IAM_ENABLED - set to true to enable IAM authentication for RDS connections.

Bugfixes​

  • Refactor the logic for creating new sessions. It now gets the previous event context directly from the database which makes the logic more robust against cases where the in-memory event stream might not have the previous event.

[3.5.9] - 2025-10-29​

Rasa Pro Services 3.5.9 (2025-10-29)

Bugfixes​
