DatastoreClient 0.0.7

Python Client for Datastore APIs

#Datastore Client

Project TCT图像与信息存储数据库 Datastore python版Client

##示例

if __name__ == "__main__":
    #test code
    #this test code shows that:
    #   crate a lot of raw datas
    #   upload them to datastore
    #   gather them togher to create a dataset name 'L-in-H'
    #   and query them out in tow style
    log.getLogger().setLevel(log.INFO)
