Add oceanbase in the database section.

OceanBase is a distributed relational database. Based on the Paxos protocol and its distributed structure, OceanBase provides high availability and linear scalability.

Key features:

• Transparent Scalability

  An OceanBase cluster can be scaled to 1,500 nodes transparently, handling petabytes of data and a trillion rows of records.

• Ultra-fast Performance

  The only distributed database that has refreshed both the TPC-C record, at 707 million tmpC, and the TPC-H record, at 15.26 million QphH @30000GB.

• Real-time Operational Analytics

  A unified system for both transactional and real-time operational analytics workloads.

• Continuous Availability

  OceanBase Database adopts the Paxos Consensus algorithm to achieve Zero RPO and less than 8 seconds of RTO. Supports intra-city/remote disaster recovery, enabling multi-activity in multiple locations and zero data loss.

• MySQL Compatible

  OceanBase Database is highly compatible with MySQL, which ensures that zero or a few modifications are needed for migration.

• Cost Efficiency

  The cutting-edge compression technology saves 70%–90% of storage costs without compromising performance. The multi-tenancy architecture achieves higher resource utilization.

Is this a software written in C++ or a library that can be used in C++ projects?

[hnwyllmm]

oceanbase is a database system written in c++. There's more than 3 million lines and there're a few interesting features such as paxos, linear scalability, storage compression. And it had taken the first place in the tpcc test a few years ago.
