@Yoskaldyr sorry to inform you that MySQL, Percona nor MariaDB currently support RHEL9. We will need to wait to v0.12.7-1

My testing using almalinux/9 and mysql_80 worked fine. We are good to go on next release.

@swechsler, the amount of jobs printed are the amount of elements in the queue, it will pause when it reaches to 200k to avoid OOM kills, but it doesn't reset...

Closing til we get more info

Hi @balusarakesh, if you want to decrease the reads, you should decrease the amoun of threads with -t

Btw what version of mydumper are you using?

Hi @balusarakesh , mydumper doesn't perform write operations in the source servers. It is myloader the one that execute the inserts.

Stage I should be reducing the amount of memory used. The Stage II will be implemented on next releases.

Chunk builder has been added and it is better understanding of the chunk that is going to be executed next time that we need to get a chunk of data...
