Crate
CrateDB is a distributed and scalable SQL database for storing and analyzing massive amounts of data in near real-time, even with complex queries. It is PostgreSQL-compatible, and based on Lucene.
Great initiative making a list of possible Rockset replacements. Would it be possible to open the Notion page for guest contributions?
I would like to add CrateDB (I work there) to the list. CrateDB is a distributed SQL database purposely built for real-time analytics across large datasets of structured and semi-structured data. Similarly to Rockset, it indexes all data in real-time (text, vector, geospatial, time-series, and JSON) for the most efficient search and fast ad hoc query execution at any scale. It is built on top of Apache Lucene and unlike Rockset is open-source (https://github.com/crate/crate).
Rocket frequently comes up among other solutions our users were looking at before choosing CrateDB. For example https://cratedb.com/customers/govspend.
