If you are using MyDumper as your Logical Backup solution and you store your backups on S3, you need to take a local backup and then upload it to S3. But what if there is not enough space to hold the backup on the server where we are taking the backup? Even if we have enough disk space, we will need to wait until the end to start to upload the files, making the whole process longer.

MyDumper implemented stream backup in v0.11.3 and we have been polishing the code since then. We also implemented two ways of executing external commands:

−−exec-per-thread: The worker that is getting the data from the database will write and redirect to the STDIN of the external command. It will be similar to execute cat FILE | command per every written and closed file.

One of the pillars of this quartet had a milestone last week when PHP 8.0 passed into End Of Life status. While it will still have limited security issue support for another year, 8.0 should be phased out of your environments.

By the way, 8.1 has another year until it reaches End of Life status.

So please update your PHP 8.0 as soon as you can, double check the connector you are using to access your database is updated too, and make sure you are ready for 8.1’s future.
