We’re happy to announce our newest open-source project, java-hll, a HyperLogLog implementation in Java that is storage-compatible with the previously released postgresql-hll and js-hll implementations. And as the rule of three dictates, we’ve also extracted the storage specification that makes them interoperable into it’s own repository. Currently, all three implementations support reading storage specification v1.0.0, while only the PostgreSQL and Java implementations fully support writing v1.0.0. We hope to bring the JS implementation up to speed, with respect to serialization, shortly.
