Overview ¶
Package mysql is the MySQL driver. mysqldump is single-threaded, so the driver gets its parallelism by splitting the tables of a database into groups and running one `mysqldump <tables> | mysql` pipe per group, balanced by table size. Both tools run inside the local mysql container towards any pair of endpoints.

func (*Driver) Plan ¶
func (d *Driver) Plan(ctx context.Context, src, dst driver.Endpoint, db string, workers int, only []string) (driver.Plan, error)
Plan: phase 1 = the selected base tables in up to `workers` size-balanced groups, phase 2 = the selected views, plus routines/events when the whole database is cloned. Each group is its own --single-transaction, so groups are not one snapshot of each other — fine for a dev copy, not for a backup.
func (*Driver) Prepare ¶
Prepare creates the database only when it is missing — a remote target user may lack the CREATE privilege on a database that already exists. db was validated by the engine.
