Greenplum Database vs Teradata VantageCloud

Greenplum Database is a PostgreSQL-based, open-source data warehouse for analytics, machine learning, and AI. Its architecture spreads data and query work across a cluster: a coordinator divides queries among segment servers. The project describes it for large analytical warehouses and business intelligence, including petabyte-scale data. Query planning can use GPORCA alongside the PostgreSQL-based planner. Storage options include append-optimized row and column formats, with compression for column storage. PXF connectors connect to Hadoop, object stores including Azure, Google Cloud Storage, MinIO, and S3, and SQL databases through JDBC. External tables can be queried or used to load outside data; PXF also supports querying Apache Iceberg foreign tables. Clients can connect through psql, ODBC, or JDBC. Greenplum is available as a free open-source project under Apache 2, while the commercial VMware Tanzu Greenplum offering is priced on request. It supports on-premises deployment and data lakes. Documented access control covers object privileges; row-level and column-level access controls are not supported.

Teradata VantageCloud, renamed Teradata Cloud in May 2026, is Teradata’s cloud deployment of its Autonomous Knowledge Platform for production AI, analytics, lakehouse, and agentic AI workloads. It is purpose-built for AWS, Microsoft Azure, and Google Cloud, with public cloud, multi-cloud, hybrid, and on-premises deployment options. Its managed system combines always-on compute with elastic capacity that scales within defined boundaries and releases resources when idle. Elastic compute can work directly with Apache Iceberg and Delta Lake tables in object storage.

The platform supports Python, R, SQL, and SAS, and lists integrations with Amazon SageMaker, AzureML, Google Vertex AI, Dataiku, and H2O.ai. External models can be imported using PMML, MOJO, ONNX, or MLeap. In hybrid deployments, data remains in its original environment unless configured to move. Teradata lists HIPAA, HITRUST, ISO/IEC 27001, ISO 27017, PCI DSS, SOC 1 Type II, SOC 2 Type II, and GDPR among its programs and commitments. A free trial offers an interactive sandbox and more than 250 guided demos without requiring a credit card; no trial duration is stated. The ClearScape Analytics Experience is free. Teradata Cloud pricing is on request; listed Lake packages use a $1.50 per unit base rate, with package-specific rates described separately.
