DMS

Distributed Memory Service (DMS) is a foundational component providing distributed memory services.
It supports the transmission of PAGE content over TCP/RDMA networks, merging primary and standby memory to provide real-time page exchange capabilities. This enables real-time consistent read functionality on standby nodes.

2. Downloading DMS

Download DMS from the open-source community.

3. Compiling Code

Use DMS/build/linux/opengauss/build.sh to compile the code. The following table describes the parameters.

Option	Parameter	Description
-3rd	[binarylibs path]	Specifies the binarylibs path. It must be an absolute path.
-m	[version_mode]	Specifies the target version of the compilation. It can be Debug or Release (default).
-t	[build_tool]	Specifies the compilation tool, which can be cmake (default) or make.

Run the following command to perform compilation:
[user@linux ]$ sh build.sh -3rd [binarylibs path] -m Release -t cmake
After the compilation is complete, the dynamic library is generated under the DMS/output/lib directory.
