There Are a Lot of Databases

I was reading Andy Pavlo's end-of-year review of the database world. He's done this for a number of years, and there are links to previous recaps in the piece. He is an associate computer science professor at Carnegie Mellon University, working on quite a few database-related projects. In the review, he tends to track the database world from the perspective of business success and money. There are certainly parts of it that discuss technical changes, but my overall impression is more about the business and usage success than it is about the way database systems work. The main thing that struck me after reading the review was how many database systems there are in the world. I hadn't heard of any of these: RaptorDB, TigerData, Tembo, StormDB, Translattice, FerretDB, DocDB, SpiralDB, Tantivy, SkySQL, HeavyDB, and more. I'm sure I missed listing some I didn't recognize, and quite a few of these are PostgreSQL-based systems, but still, that's a lot of database systems that exist and are having success.
