So what's the best practice for when you want a real time dashboard but also want the ability to compare data overtime. E.g., ave. bounce rate this month vs last? Is Pipeline still ideal in this case?
Jeff (PipelineDB Co-Founder, here) - Yes, PipelineDB is great for this use case. One powerful aspect of PipelineDB is that it is a fully functional relational database (a superset of PostgreSQL 9.4) in addition to a streaming-SQL engine we have integrated the notion of 'state' into stream processing, for use cases exactly like this.
You can do anything with PipelineDB that you can do with PostgreSQL 9.4, but with the addition of continuous SQL queries, sliding windows, probabilistic data structures, uniques counting, and stream-table JOINs (what you're looking for here, I believe.)
