Time for our weekly review of the news! The big news this week is that Percona XtraBackup is ready to try out on Windows. Otherwise, there’s just more steady progress. One quick note, sort of a “to whom it may concern,” is that the proper trademarked names of our products include “Percona Server”, “Percona XtraDB”, […]

Upstream from the replicas is the primary, which enables replication by writing a so-called “binary log” of events that modify data in the server. The binary log is […]
