Flink SQL enables engineers to write streaming queries in familiar SQL syntax, joining Kafka streams with database lookups in real time. Flink is preferred over Spark Streaming for use cases requiring low latency (sub-second) processing and stateful computations across unbounded event streams.
Python data engineers use PipelineDB via standard `psycopg2` connections — defining continuous views in SQL that automatically aggregate incoming rows. A Python ingestion process writes events to PipelineDB streams using standard INSERT statements, and the continuous view query results update in real time, making precomputed aggregates instantly available for dashboards.
