- `kafka_partitions`：指定待消费的 partition 列表，如："0, 1, 2, 3"。
- `kafka_offsets`：指定每个分区的起始offset，必须和 `kafka_partitions` 列表个数对应。如："1000, 1000, 2000, 2000"
- `property.kafka_default_offset`：指定分区默认的起始offset。
- `property.kafka_default_offsets：指定分区默认的起始offset。
在创建导入作业时，这三个参数可以有以下组合：
| 组合 | `kafka_partitions` | `kafka_offsets` | `property.kafka_default_offset` | 行为 |
| 组合 | `kafka_partitions` | `kafka_offsets` | `property.kafka_default_offsets` | 行为 |
| ---- | ------------------ | --------------- | ------------------------------- | ------------------------------------------------------------ |
| 1 | No | No | No | 系统会自动查找topic对应的所有分区并从 OFFSET_END 开始消费 |
| 2 | No | No | Yes | 系统会自动查找topic对应的所有分区并从 default offset 指定的位置开始消费 |
