Experience True Incremental View Maintenance
Batch jobs waste 99.9% of their time re-processing data that hasn’t changed. Feldera erases that waste with automatic incremental updates for any SQL pipeline. Process 40K-line SQL pipelines with hundreds of joins and even recursive queries, at millions of changes per second, even on a laptop.

Core platform capabilities
Experience unmatched performance, scale and expressive power for incremental computation use cases.
Powerful
Fully Incremental Compute
- Keep your compute proportional to the size of the "change", not the size of the whole dataset
- Sub-second results when data changes, even over terabytes of data
- Handles complex SQL with mathematically guaranteed correctness
Complete
Full SQL Parity
- Full SQL support including window functions and recursive queries
- Exact same semantics and SQL as your existing batch code -- code changes are rare
- Compare Feldera’s outputs against your existing database or warehouse for row-by-row parity
Resilient
Intelligent Infrastructure Management
- Intelligent scaling using disk and S3 for datasets larger than memory
- Run pipelines with strict least-privilege security and resource controls, fully integrated with Kubernetes
- Resilience via fault-tolerance and checkpointing

Frequently asked questions
How many joins can Feldera handle?
Where others struggle with 1-2 joins or large scale, Feldera is comfortable doing 500+ joins on 40K+ lines of SQL. One real-world example from production: 217 join operators, left joins included, over 250 million rows, updating in about 200ms on a single 16-core machine. See the real world example
Does Feldera support recursive SQL queries?
Yes. Feldera supports recursive and mutually recursive views through its own DECLARE RECURSIVE VIEW syntax, which is more expressive than standard SQL recursion. Read the docs
Which SQL does Feldera support?
Feldera compiles SQL with Apache Calcite and supports aggregates, joins including outer joins, DISTINCT, window functions, JSON and variant types, arrays, maps, and table functions. Declare a view MATERIALIZED and it becomes queryable state: point ad hoc SQL at it and you get the latest result. Read the docs
Is Feldera open source?
Yes. The open source edition is MIT licensed: single node, full SQL support, all connectors. Enterprise is for production at scale: self-hosted in your own Kubernetes clusters, with multi-node deployments, fault tolerance, disaster recovery, SSO, and RBAC. Your pipelines, code, and data stay inside your perimeter. Try today
