AStream: Ad-hoc Shared Stream Processing

Summary: First distributed ad-hoc shared stream processing framework on Apache Flink, enabling multi-tenant ad-hoc queries to share computation. Composable integration for joins, aggregations, and windows with exactly-once, incremental execution; yields high throughput for many concurrent queries (comparable to Flink for one query, orders of magnitude better for many).
