How does this impact PipelineDB? Sounds similar if not identical.
Jeff from PipelineDB here. Our products are similar in that they execute SQL queries continuously on streaming data, but the main differences are that PipelineDB is 1) open-source, and 2) includes a fully functional relational database, which enables "state" and doesn't presume that data is intended to be streamed out as well as in. The latter is a seemingly subtle, but important difference because "stream out only" drastically limits use cases.
