In general the position where the storage recovers after a SST cannot be known untile the recovery process is over. This in turn means that the position cannot be known when the server_state sst_received() method is called. Worked around the problem by introducing get_position() method into server service which can be used to get the position from stable storage after SST has completed and the state has been recovered.
Introduction
Project name: wsrep-lib - Integration library for WSREP API
The purpose of this project is to implement C++ wrapper for wsrep API with additional convenience for transaction processing.
This project will abstract away most of the transaction state management required on DBMS side and will provide simple C++ interface for key set population, data set population, commit processing, write set applying etc.
Build Instructions
In order to build the library, run
cmake . make
