type Job

type Job interface {
	MsgID() int64
	CollectionID() int64
	Context() context.Context
	// PreExecute does checks, DO NOT persists any thing within this stage,
	PreExecute() error
	// Execute processes the request
	Execute() error
	// PostExecute clears resources, it will be always processed
	PostExecute()
	Error() error
	SetError(err error)
	Done()
	Wait() error
}

Job is request of loading/releasing collection/partitions, the execution flow is: 1. PreExecute() 2. Execute(), skip this step if PreExecute() failed 3. PostExecute()
