think SST/IST failed, at next restart will request a full SST This patch fixes an unwanted behavior of a Galera cluster node when Server startup fails because of an error in configuration file: after the failure full SST is requested at the next Server startup even though full SST is not needed (MDEV-31517). If Server startup fails because of a configuration error, this patch ensures that Galera state of the failing node remains unchanged. This avoids full SST at the next Server restart. This fix consists of three patches for the following components: 1) Server, 2) WSREP library, 3) Galera.
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.
