ETL Structured and Unstructured Data into a Knowledge Graph with Tom Sawyer Data Streams 1.0

Join us February 25, 2026 at 8 a.m. PST for this live webinar

Join our live webinar with Thanos Giannakis, Senior Product Development Engineer at Tom Sawyer Software, as he demonstrates Tom Sawyer Data Streams 1.0. This first public release of our new platform builds on the successful beta by adding capabilities that improve real-time data fidelity, operational safety, and developer productivity. 

Tom Sawyer Data Streams unifies streaming and legacy data into a single, governed, query-ready knowledge graph you own. Subscribe to Apache Kafka (or Confluent) topics sourced from databases, files, and APIs; apply precise transformations and filters; then run flows continuously to normalize, enrich, and link changing streams in real time. 

Discover how Tom Sawyer Data Streams reduces integration effort and delivers a complete, accurate picture for lineage, impact analysis, and operational decisions.

Thanos Giannakis, Senior Product Development Engineer at Tom Sawyer Software, demonstrates how Data Streams reduces integration efforts and unifies data into a query-ready knowledge graph you own.

What to expect

During this live webinar, attendees will learn how to:

  • Subscribe to Apache Kafka (or Confluent) topics, then transform and persist those events into a knowledge graph model

  • Automatically extract schemas from Kafka topics, refine them in a visual editor, and apply advanced filters and rules with Spring Expression Language (SpEL)

  • Use the web-based designer to define sources, transformations, conditions, and sinks to build and monitor data flows

  • Run flows in batch or continuously to ingest and transform events as they arrive

  • Persist transformed data to a graph database and publish results back to Kafka for downstream services

  • Pair Data Streams with Tom Sawyer Perspectives or Tom Sawyer Explorations for advanced graph and data visualization and analysis

  • Discover how Data Streams can prepare and process data for LLMs, validate generative AI outputs, and unify agentic results in a governed single source of truth
