What Is New in Embedded MPP 9.20250929

This page lists the main enhancements of the Denodo Embedded MPP 9.20250929.

Presto

  • Add support for Bearer Token Authentication to connect to the Nessie catalog.

  • Add support for adding and dropping table columns on the Hive catalog to support schema evolution in cached tables when the Embedded MPP is configured as the cache system.

  • Now the Test Connection of the Embedded MPP data source will display the Embedded MPP version, not only the Presto version.

  • The MPP image container now includes the less package, ensuring that Presto CLI outputs (such as large query results) can be displayed.

  • Remove optimizer.join-reordering-strategy and join-distribution-type to simplify configuration, as these properties are enabled by default.

Hive Metastore

  • The target PostgreSQL schema can be parameterized. Now, the MPP do not assume that Hive Metastore tables would always be created in the default PUBLIC schema.

  • Initialization of the Hive Metastore now only occurs if the target schema does not already exist.

Helm and Kubernetes

  • Add support for specifying custom annotations on all major resources, including Services, Deployments, and Pods.

  • A new section for common customized labels has been introduced in values.yaml

  • Now, the register.sh script ignores parameters of values.yaml that are commented out.

  • Add a reference to REGISTER_EMBEDDED_MPP stored procedure in the Notes displayed after the helm install command.

  • Fixed an issue in register.sh where the script incorrectly appended the port number to the service URI when Ingress was enabled.

  • Properties marked for removal in version 10.x are now officially deprecated in this 9.x release.
