# DeltaStream
> DeltaStream is the real-time context engine for AI agents — a serverless, unified analytics platform that continuously computes live context from streaming data and delivers it to AI agents via a built-in MCP server. Founded in 2021, DeltaStream eliminates tool fragmentation by merging streaming, batch, and real-time analytics into a single SQL-driven platform powered by Apache Flink, Apache Spark, and ClickHouse.

## Product

- [DeltaStream Fusion](https://www.deltastream.io/product/deltastream-fusion/): The core product — a serverless unified analytics platform combining streaming, batch, and real-time processing. Write SQL; DeltaStream routes queries to the optimal engine automatically. Available as managed SaaS or private SaaS (BYOC).

## Solutions

- [Agentic AI](https://www.deltastream.io/solutions/agentic-ai/): Powers AI agents with continuously refreshed real-time context, preventing hallucinations from stale data. Includes built-in MCP server, streaming materialized views, intelligent pipeline filtering, and cost controls that reduce unnecessary LLM calls.
- [Cost Optimization](https://www.deltastream.io/solutions/cost-optimization/): Reduces data warehouse and infrastructure costs by replacing fragmented tooling with a single serverless platform that scales automatically.
- [Batch to Streaming](https://www.deltastream.io/solutions/batch-to-streaming/): Migrates batch workloads to real-time streaming without rewriting logic — SQL queries run on Flink, Spark, or ClickHouse depending on the workload type.

## Integrations

- [Integrations](https://www.deltastream.io/integrations/): Native connectors for Apache Kafka, AWS Kinesis, Redpanda, Snowflake, Databricks Lakehouse, Apache Iceberg (with Glue and REST catalogs), ClickHouse, Debezium (CDC), and more.
