What is TcaplusDB?
TcaplusDB is a distributed database developed by Tencent independently that features low cost, high availability, high reliability and high performance. TcaplusDB’s design is based on the development characteristics and OPS requirements of games and provides 7x24 game data storage service that is easy to use and features high performance, low cost, high scalability, 99.999% availability and data security, so that game developers no longer worry about data storage.
What business scenarios is TcaplusDB suitable for?
TcaplusDB is created for games, including mobile games, PC games and browser games. It is also suitable for other storage scenarios, such as social network, e-commerce, and government websites and apps.
Which client languages are supported by TcaplusDB?
Linux platform: C++, Java, Erlang; Windows platform: C++, Java, Erlang. Tdr and Protobuf are provided to define app data table structure, and the object-oriented method is adopted. API network communication modes include: message-driven asynchronous operation mode, function callback asynchronous operation mode, coroutine operation mode, and dbproxy proxy mode. Game developers who adopt a language other than C++/Java can access TcaplusDB via RestAPI.
