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
