The new MyDumper 0.12.3-1 version, which includes many new features and bug fixes, is now available. You can download the code from here. MyDumper is Open Source and maintained by the community, it is not a Percona, MariaDB, or MySQL product.
In this new version we focused on:
- Refactoring tasks: Splitting mydumper.c and myloader.c into multiple files will allow us to find bugs and implement features easily.
- Adding compression capabilities on stream: One of the more interesting features added to MyDumper was being able to stream to another server and now, compression and transmission will be available and much faster.
- Support for the Percona Monitoring and Management (PMM) tool: Being able to monitor scheduled processes is always desired, even more, if you know what the process is doing internally and that is why we used the textfile extended metrics to show how many jobs have been done and queue status.
Enhancement:
- Adding PMM support for MyDumper #660 #587
- Adding compression capabilities on stream #605
- Dockerfile: use multi-stage builds #603

- Adding critical message when DDL fails #636 #634
- Fix print time #633 #632

- Dockerfile: add missing libglib2.0 package #608
- [BUG] mydumper zstd doesn’t run on CentOS due to missing libzstd package dependency #602
Refactoring:
- Reengineering the DDL locks and connection sync #619 #484 #383 #254 #8
- Spliting mydumper.c #609 #646 #607

How should I stop graceful the MyLoader in progress to avoid a rollback process the transaction started by load process?
I understand that a big transaction that is running by 4 hours will take so long to rollback.
Hi Renan, you should run mydumper with -r and/or -F to avoid having big transactions.
