Feldera

Purpose: Feldera is an incremental view maintenance engine that keeps SQL views in sync with changing data and works alongside a lakehouse or warehouse.
Incremental updates: When input tables change, Feldera incrementally updates views in proportion to the change rather than the full dataset.
SQL support: Feldera supports SQL including window functions and recursive queries.
Performance: The product page says Feldera can process complex pipelines with millions of changes per second, including on a laptop.
Inputs: Documented input connectors include Kafka, Google Pub/Sub, NATS, PostgreSQL, AWS S3, Delta Lake, and Apache Iceberg.
Outputs: Documented output connectors include Kafka, Delta Lake, PostgreSQL, Redis, DynamoDB, Snowflake, and Iceberg; several are marked experimental.
Deployment: Feldera offers Docker for local development, testing, and prototyping, a free online sandbox, and an enterprise offering for production.
Enterprise hosting: Enterprise runs on a customer-provided cloud or Kubernetes cluster, and the documentation says data never leaves the customer's premises.
Enterprise capabilities: Enterprise adds multi-node clusters, pipeline and control-plane fault tolerance, resource isolation, and dedicated support; pipeline scale-out is listed as coming soon.
Security: The Trust Center lists SOC 2 Type 1 and Type 2 compliance and offers access to security documentation, including a penetration test report and SOC 2 report.
Use cases: Feldera presents real-time medallion architectures, fraud detection feature engineering, and fine-grained authorization as use cases.
Community support: The open source edition provides community support through Slack.
Company history: Feldera says its founders had worked on incremental computation challenges since 2018 and that its technology had run in production at VMware since 2021.
