EDB’s vision for analytics on Postgres

EDB implements modern analytics patterns through the Analytics Accelerator, enabling Postgres to serve as a unified platform for both operational and analytical workloads.

Key principles:

  • Perform analytics close to operational data, reducing data movement and latency
  • Use open formats and vectorized query engines for fast analytics on object storage
  • Support data tiering to balance cost and performance
  • Separate compute and storage to allow independent scaling
  • Manage the entire stack via Hybrid Manager

Key EDB solutions and technologies

EDB Postgres Lakehouse

Lakehouse architecture enables EDB Postgres to query data in object storage:

  • Lakehouse nodes query data in open table formats (Iceberg, Delta Lake)
  • Vectorized query execution powered by Apache DataFusion
  • Columnar storage formats such as Parquet
  • Separation of compute and storage

Vectorized query optimization

Analytics Accelerator embeds Apache DataFusion in Lakehouse nodes:

  • Processes data as columnar batches
  • Uses SIMD instructions to accelerate performance
  • Optimized for Parquet-formatted data

Related concept: Vectorized query engines

EDB Postgres Distributed (PGD) and Tiered Tables

EDB Postgres Distributed (PGD) powers Tiered Tables:

  • BDR AutoPartition manages time-based partitioning
  • Cold data is automatically offloaded to object storage (Iceberg tables)
  • Hot data remains in transactional PGD nodes

This balances operational performance with cost-efficient historical data access.

Advanced query optimization

Analytics Accelerator improves core Postgres capabilities for analytics:

  • Enhanced parallel query processing
  • Optimized join algorithms for analytical workloads
  • Tight integration with vectorized engines for high-performance OLAP queries

Related concept: OLAP / OLTP

Analytics and AI/ML workloads

Analytics Accelerator supports traditional analytics and AI/ML data pipelines:

  • Lakehouse nodes provide efficient access to large datasets used in model training
  • Tiered data pipelines support cost-effective AI/ML staging patterns
  • Open table formats enable integration with vector search and retrieval augmented generation (RAG) workflows

How EDB implements analytics across products

Hybrid Manager (HM)

Hybrid Manager acts as the control plane:

  • Provision and manage Lakehouse clusters
  • Configure and monitor Tiered Tables
  • Manage storage locations, catalog connections, and compute nodes

EDB Postgres Advanced Server / Extended Server

EDB Postgres Advanced Server adds:

  • Improved parallel query capabilities
  • Advanced SQL features helpful for analytics
  • Native support for PGAA (Postgres Generic Analytics Adapter) features

EDB Postgres Distributed (PGD)

PGD provides the foundation for:

  • High-availability transactional workloads
  • Data tiering and offloading (Tiered Tables)
  • Scalable architectures that integrate with Lakehouse clusters
