What Is New in Embedded MPP 8.0.20251127

This page lists the main enhancements of the Denodo Embedded MPP 8.0.20251127.

Presto

  • Includes the latest Presto version, 0.295, which provides enhanced performance, security and stability.

  • Applies configuration adjustments to improve query performance. Benchmark testing on TPC-H SF1000 showed an average 10% boost in overall performance for read-only queries.

  • Adds support for collecting histogram statistics for Iceberg tables. Using histograms provides more accurate row count estimate following filter operations, especially on skewed data. This feature is disabled by default. It should be enabled when managing skewed data to take advantage of the improved statistics.

  • Enables access to the Nessie catalog and S3 storage via the Iceberg REST Catalog. This allows users to leverage OAuth 2.0 authentication by setting the iceberg.rest.auth.oauth2.credential property, which automates refresh token handling and token expiration management, eliminating the need for manual token workflows.

  • Includes the JMX Prometheus exporter to facilitate monitorization using Prometheus.

  • Includes the OpenTelemetry agent to facilitate metric collection via OpenTelemetry.

Helm and Kubernetes

  • Fixes an issue in the register.sh script that failed to append the mandatory port number to the service URI when Ingress was enabled. This ensures correct service registration when using an Ingress.
