示例1: Get

func (dm *domainMap) Get(store kv.Storage) (d *domain.Domain, err error) {
	key := store.UUID()
	dm.mu.Lock()
	defer dm.mu.Unlock()
	d = dm.domains[key]
	if d != nil {
		return
	}

	if SchemaLease <= minSchemaLease {
		SchemaLease = minSchemaLease
	}

	lease := SchemaLease
	// if storage is local storage, we may in test environment or
	// run server in single machine mode, so we don't need wait
	// 2 * lease time for DDL operation.
	if localstore.IsLocalStore(store) {
		lease = 0
	}
	d, err = domain.NewDomain(store, lease)
	if err != nil {
		return nil, errors.Trace(err)
	}
	dm.domains[key] = d
	return
}
