MySQL Group replication requirements

  • In order to integrate with this charm, every table created by the integrated application must have a primary key. This is required by the group replication plugin enabled in this charm.
  • The count of Charmed MySQL units in a single Juju application is limited to 9. Unit 10+ will start; however, they will not join the cluster but sleep in a hot-swap reserve.

Hardware

Make sure your machine meets the following requirements:

  • 8GB of RAM.
  • 2 CPU threads.
  • At least 20GB of available storage.

The charm is based on the charmed-mysql snap. It currently supports:

  • amd64
  • arm64 (from revision 274+)

Networking

  • Access to the internet for downloading the required snaps and charms.
  • Only IPv4 is supported at the moment
