This is a library that allows any arbitrary C++ application to connect to a Mysql replication master and read/parse the replication binary logs.
In effect, any application can now act like a Mysql replication slave, without having to compile or link with any Mysql server code.
One important use-case for this library is for receiving changes in the master database in real-time, without having the store the master's data on the client server.
- Statistics of rps and time of every event in every table.
- Support for mysql options:
For building the library, you will need:
g++ with C++11 support.
The standard mysql C client libraries (libmysqlclient):
- for 5.6-5.7 versions you will need place hash.h from mysql repo into your mysql include directory.
The headers of the boost libraries (http://www.boost.org). At the minimum, you will need at least the any.hpp. If boost_unit_test_framework is found, tests will be built.
You (likely) will need to review and edit the contents of Logging.h and SlaveStats.h These headers contain the compile-time configuration of the logging and monitoring subsystems. The provided defaults are sub-standard and an example only.
- Requires >= Mysql 5.1.23 and <= Mysql 5.7.12. Tested with some of the 5.1, 5.5, 5.6, 5.7 versions of mysql servers.
Create directory "build" in source tree, step into it and run "cmake ..". Then, if configure step is complete, run "make".
Review and edit Logging.h and SlaveStats.h to interface the library to your app's logging and monitoring subsystems.
You can type "make test" inside of "build" directory to run tests. You will need a working mysql server for it. Settings of mysql connection can be adjusted in test/data/mysql.conf. Type "ctest -V" if something went wrong and you need see test output.
Using the library
Please see the examples in 'test/'.
