红帽全球峰会141.7. HBase 映射
上面提到了，默认的映射策略是 标题和正文 映射。
您可以在下面找到一些有关每个映射策略如何工作的详细示例。
141.7.1. HBase 标头映射示例
标头映射是默认映射。将值 "myvalue" 放入 HBase row "myrow" and column "myfamily:mycolum" 中，消息应包含以下标头：
| 标头 | 值 |
|---|---|
| CamelHBaseRowId | myrow |
| CamelHBaseFamily | myfamily |
| CamelHBaseQualifier | myqualifier |
| CamelHBaseValue | myvalue |
要为不同的列和/或不同的行放置更多值，您可以使用标头的索引指定附加标头后缀，例如：
| 标头 | 值 |
|---|---|
| CamelHBaseRowId | myrow |
| CamelHBaseFamily | myfamily |
| CamelHBaseQualifier | myqualifier |
| CamelHBaseValue | myvalue |
| CamelHBaseRowId2 | myrow2 |
| CamelHBaseFamily2 | myfamily |
| CamelHBaseQualifier2 | myqualifier |
| CamelHBaseValue2 | myvalue2 |
对于检索操作，如 get 或 scan，您还可以为希望数据转换为的类型的每个列指定。对于考试速度：
| 标头 | 值 |
|---|---|
| CamelHBaseFamily | myfamily |
| CamelHBaseQualifier | myqualifier |
| CamelHBaseValueType | Long |
请注意，为了避免对所有消息常见的样板标头，您也可以将它们指定为端点 uri 的一部分，如下所示。
