charms.mysql.v0.backups

MySQL helper class for backups and restores.

The MySQLBackups class can be instantiated by a MySQL charm , and contains event handlers for list-backups, create-backup and restore backup actions. These actions must be added to the actions.yaml file.

An example of instantiating the MySQLBackups:

from charms.data_platform_libs.v0.s3 import S3Requirer
from charms.mysql.v0.backups import MySQLBackups
from charms.mysql.v0.backups import MySQLBase


class MySQL(MySQLBase):
    def __init__(self, *args):
        super().__init__(*args)

        self.s3_integrator = S3Requirer(self, "s3-integrator")
        self.backups = MySQLBackups(self, self.s3_integrator)

    @property
    def s3_integrator_relation_exists(self) -> bool:
        # Returns whether a relation with the s3-integrator exists
        return bool(self.model.get_relation(S3_INTEGRATOR_RELATION_NAME))

    def is_unit_blocked(self) -> bool:
        # Returns whether the unit is in blocked state and should run any operations
        return False
