Put Operations.
HBase is a column based store, which allows you to store data into a specific column of a specific row. Columns are grouped into families, so in order to specify a column you need to specify the column family and the qualifier of that column. To store data into a specific column you need to specify both the column and the row.

If the role of the rowModel is not clear, it allows you to construct the HBaseRow modle programmatically instead of "describing" it with uri options (such as family, qualifier, type etc).

The header mapping is the default mapping.
To put the value "myvalue" into HBase row "myrow" and column "myfamily:mycolum" the message should contain the following headers:
Div |
---|
class | confluenceTableSmall |
---|
|
Header | Value |
---|
CamelHBaseRowId | myrow | CamelHBaseFamily | myfamily | CamelHBaseQualifier | myqualifier | CamelHBaseValue | myvalue |
|
Wiki Markup |
---|
{div:class=confluenceTableSmall}
|| Header || Value ||
| CamelHBaseRowId | myrow |
| CamelHBaseFamily | myfamily |
| CamelHBaseQualifier | myqualifier |
| CamelHBaseValue | myvalue |
{div} |
To put more values for different columns and / or different rows you can specify additional headers suffixed with the index of the headers, e.g:
Div |
---|
class | confluenceTableSmall |
---|
|
Header | Value |
---|
CamelHBaseRowId | myrow | CamelHBaseFamily | myfamily | CamelHBaseQualifier | myqualifier | CamelHBaseValue | myvalue | CamelHBaseRowId2 | myrow2 | CamelHBaseFamily2 | myfamily | CamelHBaseQualifier2 | myqualifier | CamelHBaseValue2 | myvalue2 |
|
Wiki Markup |
---|
{div:class=confluenceTableSmall}
|| Header || Value ||
| CamelHBaseRowId | myrow |
| CamelHBaseFamily | myfamily |
| CamelHBaseQualifier | myqualifier |
| CamelHBaseValue | myvalue |
| CamelHBaseRowId2 | myrow2 |
| CamelHBaseFamily2 | myfamily |
| CamelHBaseQualifier2 | myqualifier |
| CamelHBaseValue2 | myvalue2 |
{div} |
In the case of retrieval operations such as get or scan you can also specify for each column the type that you want the data to be converted to. For exampe:
Div |
---|
class | confluenceTableSmall |
---|
|
Header | Value |
---|
CamelHBaseFamily | myfamily | CamelHBaseQualifier | myqualifier | CamelHBaseValueType | Long |
|
Wiki Markup |
---|
{div:class=confluenceTableSmall}
|| Header || Value ||
| CamelHBaseFamily | myfamily |
| CamelHBaseQualifier | myqualifier |
| CamelHBaseValueType | Long |
{div} |
Please note that in order to avoid boilerplate headers that are considered constant for all messages, you can also specify them as part of the endpoint uri, as you will see below.
