maxbube/mydumper: Official mydumper project

What is mydumper? and Why?

  • Parallelism (hence, speed) and performance (avoids expensive character set conversion routines, efficient code overall)
  • Easier to manage output (separate files for tables, dump metadata, etc, easy to view/parse data)
  • Consistency – maintains snapshot across all threads, provides accurate master and slave log positions, etc
  • Manageability – supports PCRE for specifying database and tables inclusions and exclusions

This is required when running MySQL Galera Cluster, as we’ll explain in the next section. Note that this limitation is removed in the paid-only edition called NGINX Plus.
