| 73 | +## 示例 |
| 74 | + |
| 75 | +### 表读取 |
| 76 | + |
| 77 | +```hocon |
| 78 | +source { |
| 79 | + Maxcompute { |
| 80 | + accessId="<your access id>" |
| 81 | + accesskey="<your access Key>" |
| 82 | + endpoint="<http://service.odps.aliyun.com/api>" |
| 83 | + project="<your project>" |
| 84 | + table_name="<your table name>" |
| 85 | + #partition_spec="<your partition spec>" |
| 86 | + #split_row = 10000 |
| 87 | + #read_columns = ["col1", "col2"] |
| 88 | + } |
| 89 | +} |
| 90 | +``` |
| 91 | + |
| 92 | +### 使用表列表读取 |
| 93 | + |
| 94 | +```hocon |
| 95 | +source { |
| 96 | + Maxcompute { |
| 97 | + accessId="<your access id>" |
| 98 | + accesskey="<your access Key>" |
| 99 | + endpoint="<http://service.odps.aliyun.com/api>" |
| 100 | + project="<your project>" # default project |
| 101 | + table_list = [ |
| 102 | + { |
| 103 | + table_name = "test_table" |
| 104 | + #partition_spec="<your partition spec>" |
| 105 | + #split_row = 10000 |
| 106 | + #read_columns = ["col1", "col2"] |
| 107 | + }, |
| 108 | + { |
| 109 | + project = "test_project" |
| 110 | + table_name = "test_table2" |
| 111 | + #partition_spec="<your partition spec>" |
| 112 | + #split_row = 10000 |
| 113 | + #read_columns = ["col1", "col2"] |
| 114 | + } |
| 115 | + ] |
| 116 | + } |
| 117 | +} |
| 118 | +``` |
