快速指南

首先使用atomctl命令行工具进行工作空间设置和初始化操作。然后分别启动元数据服务和atom主服务(两个服务未支持后台开启)。

以下是atomctl命令行示例:

$ atomctl set --workspace 'D:\Workspace\JiYuan\Atom\Demo\test'

$ atomctl init

$ atomctl metadata-service

$ atomctl start-service

然后就是使用python脚本进行atom的数据和算子操作。主要包括数据和算子的注册、查询、删除三个基本操作以及算子的加载操作

以下是atom主程脚本代码示例:

from atom.scheduler import *

### 加载Atom调度器
atom = AtomScheduler(mode='delay')


### register-data测试
df = pd.read_csv(r"D:\Workspace\JiYuan\WindPowerForecast\LSTM\demo\merge_data_GDTYUAN_ec.csv")
atom.data_register(tag='test',
                   belong='first',
                   object_name='merge_data_GDTYUAN_ec_1',
                   data_object=df,
                   remarks='this is a test data!')

### register-operator测试
### 即时模式----装饰器方式
# @atom.operator_register(tag='test',
#                         belong='first',
#                         object_name='test_function_a',
#                         remarks='this is a test operator!')
def test_function(a,b):
    c = a + b * 2 + 1
    return c
# tmp_a = test_function(1,2)
### 及时模式----函数方式
# tmp_func = atom.operator_register(tag='test',
#                         belong='first',
#                         object_name='test_function_b',
#                         remarks='this is a test operator!')(test_function)
# tmp_b = tmp_func(3,4)
### 延时模式
atom.operator_register(tag='test',
                       belong='first',
                       object_name='test_function_a', ## cc
                       operator_object=test_function,
                       remarks='this is a test operator!')


# ### data-remove测试
# atom.data_remove(tag='test',object_name='merge_data_GDTYUAN_ec_00')


### operator-remove测试
# atom.operator_remove(tag='test',object_name='test_function_cc')


### data-query测试
data_view_df = atom.data_query(tag='test')
print(data_view_df)


### operator-query测试
operator_view_df = atom.operator_query(tag='test')
print(operator_view_df)


### data-modify测试
atom.data_modify()


### operator-modify测试
atom.operator_modify()


### data-load测试
data_load_df = atom.data_load(tag='test',object_name='merge_data_GDTYUAN_ec_1')
print(data_load_df)


### operator-load测试
operator_load_a = atom.operator_load(tag='test',object_name='test_function_a')
print(operator_load_a(10,20))
# print(test_function(**{'a':10,'b':20})) ### 字典参数传递

最后是算子在线计算服务的使用。当一个算子注册到atom后,他就自动获得了在线计算服务的功能。

表单数据格式如下:

    ### 该表单数据仅以python为例展示
    post_form = {
"tag": "test",
"object_name": "test_function_a",
    "data_json": {"a":78,"b":9}
    }
