This dataset simulates temporal joins across multiple event streams under varied time ranges, join windows, lateness policies, state-retention periods, and watermark configurations. It includes event sequences, cross-stream match relations, join-state evolution, late-event impacts, and final or incremental outputs. The data supports analysis of how event time and arrival order affect join results and state management, as well as stream-processing engine validation, algorithm evaluation, and reasoning model training.

FAQ
Frequently Asked Questions
- What does the dataset contain?
- It includes simulation configurations, multi-source event streams, join match relations, join-state evolution, late-event impacts, join outputs, and watermark reasoning summaries. These records support tracing the process from input events to join results.
- Can the data be used to evaluate late-event handling?
- Yes. Samples cover different lateness policies and watermark conditions, recording how late events affect acceptance, dropping, retrospective matching, and join outputs. This supports analysis of late-event processing logic.
- Is this data from a production environment?
- This is generated data for simulation learning, not a record of measurements from a specific production environment. Before making deployment decisions, validate findings against the target engine, workload, and real event distributions.
- How can I access the data, and what are the licensing terms?
- Check the dataset product page for available formats, samples, delivery options, and licensing terms. Download permissions and permitted uses are subject to the terms published on that page.
