InfluxDB
Power Real-Time Data Analytics at Scale. Get real-time insights from all types of time series data with InfluxDB. Ingest, query, and analyze billions of data points in real-time with unbounded cardinality.
The datalevin project's readme lists some other alternatives at the bottom of the readme as well. Not everyone agrees with the comparison, but the list is there.
Our release 0.3.3 of today dramatically speeds up batch write speed and should be in a similar ballbark as Datalevin for batch inserts now (100k datoms in 5 secs on my machine) while not sacrificing the persistency of the underlying datastructures. We are aware of our suboptimal query performance and are designing a new runtime at the moment. If you are interested or can provide feedback, please join our weekly reading group about Datalog implementations on our Discord server https://discord.gg/kEBzMvb. Help and input is very welcome! Currently we are also working towards a fully global address space and connection management including interfaces that explicitly generalize the semantics of Datahike to non-Clojure runtimes.
