coyote

a systemd service for migrating a live atlas cluster to a self-hosted cluster

coyote uses mongodump and mongorestore to perform:

• a point in time restore (pitr) of a live source cluster to a new target cluster
• subsequent source operation log replays on the target, in perpetuity, to keep target synced with source until the source goes offline
