OceanBase

OceanBase is a distributed relational database developed by Ant Group. It uses Paxos replication, is MySQL compatible and can handle hybrid transactional and analytical workloads. The project is published on GitHub, and its README states that it is licensed under Apache-2.0, although that statement was not checked against the licence file itself, so buyers should read the file before relying on it. It can be run self-managed, and this listing has not verified whether a cloud service is offered. Pricing is not published. Anyone evaluating OceanBase should therefore check the repository releases page for the current version and its support status. Because the project is distributed and replicates with Paxos, it is typically evaluated by teams that need data to stay consistent across several nodes, and a pilot is the most reliable way to test whether its MySQL compatibility covers a particular application. Buyers who need commercial support should ask the vendor directly.
