TcaplusDB is a distributed NoSQL database specially designed for additional optimization of the game. As a part of Tencent Cloud database service, TcaplusDB provides customers with the ultimate game data experience. At present, it has provided stable data storage services for more than 10 million DAU titles. Relying on Tencent cloud’s infrastructure service nodes across five continents (Asia, Europe, North America, South America and Oceania), game developers only need to access once to facilitate global game user experience.
As a high-performance distributed NOSQL database, TcaplusDB can be well deployed and run in Intel x86-64 architecture server environment (ARM architecture server environment) and mainstream virtualization environment, and supports most mainstream hardware networks. As a high-performance database system, TcaplusDB supports the mainstream Linux operating system environment.

Linux operating system platform
version
Red Hat Enterprise Linux
6.x – 7.x
CentOS
6.x – 7.x
Tlinux
1.2/2.2
Note:
-
The TcaplusDB has been extensively tested in CentOS 6.x and CentOS 7.x environments, and there are many best practices for deploying this operating system in operation cases. Therefore, it is recommended to use a Linux operating system with CentOS 7.3 or higher.
-
The preceding Linux operating systems can run on physical servers and mainstream hypervisors such as VMware, KVM, XEN, and Docker
2. You are advised to configure the server
TcaplusDB supports the deployment and running of 64-bit generic hardware server platforms on Intel x86-64 architecture (or hardware server platforms based on ARM architecture). There are the following requirements and recommendations for server hardware configuration (excluding the use of the operating system OS itself) for development, test, and production environments:

Note:
-
A higher server instance configuration is highly recommended for production environments
-
Tcapsvr Physical servers are recommended
-
To improve performance by vertical scaling, configure higher memory and local storage (NVME disks are recommended) for Tcapsvr and higher PU and memory for Tcaproxy.
-
When horizontal scaling is required to improve performance, Tcapsvr and Tcaproxy can configure more instances.
-
In the production environment, Tcaproxy and Tcapsvr can be deployed and run on the same server instance. If higher performance and reliability requirements are required, deploy them separately.
-
Tcapsvr The maximum capacity of SSD/NVME disks on the local storage cannot exceed 70% (performance deteriorates if the capacity exceeds 70% due to hardware requirements).
2.3. Network requirements
The TcaplusDB is a high-performance distributed NOSQL database. The network environment must provide the following network port configuration requirements for normal operation of the TcaplusDB. You can enable ports on the network and hosts based on the DEPLOYMENT scheme of the TcaplusDB component:
