Hi Sergei, thanks for the comment. Currently tried to just add very simple change which will allow the user to specify partition name using comma separated list and a separator in table's name. For example ./mariadb-dump -umyuser -pmypass -h127.0.0.1 mydatabase _test1@p0,p1 _test2@p0 --partition-separator=@, not sure if I should parse the partition string to ensure there's no syntax error in generated query and partition names are escaped? Maybe will add ability to do that in parallel, automatically when i'll become more familiar with the framework. Thanks, Slawomir.

Depending on your use case you might want to extend --parallel to automatically dump individual partitions in parallel, instead of extending mariadb-dump to allow to specify what partition to dump. Depends on what you need, of course, I'm just listing the options so that you could choose what works better for you.

So the idea is to run each partition in parallel using mariadb-dump but AFAIK there&#39;s no option for specifying the partition yet. Will you merge my code if I add that to mariadb-dump ? I assume MariaDB/server/blob/main/client/mysqldump.cc is where dev for that happens? Thanks Regards, Sergei Chief Architect, MariaDB Server and [email protected]
