Hey. Hybrid in which sense? I have integrated Stratum's columnar indices as a secondary index in the new query engine of https://github.com/replikativ/datahike itself, so for numerical data you will be able to use

Hi HN - I’m the author of Stratum. The headline benchmark result is that on 10M rows, Stratum is faster than DuckDB on 35 of 46 single-threaded analytical queries, despite running entirely on the JVM. But the main idea is actually branchabl

Hi HN - I’m the author of Stratum. Stratum is a columnar SQL engine built on the JVM exploring two ideas: • SIMD execution using the Java Vector API • copy-on-write branching for tables It speaks the PostgreSQL wire protocol, so tools like

I see, so your problem was that you wanted to scan over all Datoms for one entity over a time period and you would have needed to have an EVAT index? In Datahike it would be fairly simple to add new indices like this. Yes, access management

Interesting, honestly speaking we have not thought about time series data a lot yet, but I think we should be able to provide custom indices and extend Datalog with more efficient query primitives, if this is necessary. Can you elaborate a

Hey, one of the core architects of Datahike here. As a Clojure company we are also super happy that Nubank made Clojure and Datomic much more credible with this move. While Datomic is obviously much more mature, it is important to understan
