  README describes an open-source machine learning database deployed in hundreds of enterprise applications, with no paid tier, enterprise edition or license-key-gated build beside the Apache-2.0 engine.

OpenMLDB declares no package artifact: the openmldb package on PyPI is a client SDK for a running cluster, not the cluster engine itself, so it is left out rather than counted and ignored. With no deployment count published either, GitHub stars are the only adoption signal available.

OpenMLDB is a complete, highly available distributed database that computes SQL-defined features consistently across offline batch and online serving, with its own persistence and replication. It retrieves and computes features rather than hosting ranking or embedding models inside a serving path, which is what Vespa does and what keeps OpenMLDB one step below it.

  README documents a distributed, highly-available machine learning database with consistent offline and online feature computation, deployed as a cluster.
