Summary

This website describes a data streaming and querying platform focused on real-time market data. Key features include:

* Developer-friendly SQL: Designed for easy SQL writing.
* Time-bucketing: Allows resampling data into fixed intervals (e.g., 1m, 1s) for efficient querying.
* Materialized Views: Supports creating materialized views for pre-aggregated data, including a 1-second BBO view with daily TTL.
* Multi-Dimensional Arrays: Enables querying data using array operations (e.g., calculating bid/ask volume ratios).
* Time-Bounded Joins: Supports joining data based on time tolerances (e.g., 1s) for near real-time analysis.
* High Performance: Engineered for handling large datasets (terabytes daily) with sub-millisecond query speeds.
* Cloud-Native Architecture: Designed for seamless integration with cloud microservices and offers 99.9 uptime.
* Open Standards: Supports standard SQL and data formats like Parquet and Iceberg.
