=== Convert Processor
|
||
|
|
Converts a field in the currently ingested document to a different type, such as converting a string to an integer.
|
||
|
|
If the field value is an array, all members will be converted.
|
||
|
|
|
||
|
|
The supported types include: `integer`, `long`, `float`, `double`, `string`, `boolean`, and `auto`.
|
||
|
|
|
||
|
|
Specifying `boolean` will set the field to true if its string value is equal to `true` (ignore case), to
|
||
|
|
false if its string value is equal to `false` (ignore case), or it will throw an exception otherwise.
|
||
|
|
|
||
|
|
Specifying `auto` will attempt to convert the string-valued `field` into the closest non-string type.
|
||
|
|
For example, a field whose value is `"true"` will be converted to its respective boolean type: `true`. Do note
|
||
|
|
that float takes precedence of double in `auto`. A value of `"242.15"` will "automatically" be converted to
|
||
|
|
`242.15` of type `float`. If a provided field cannot be appropriately converted, the Convert Processor will
|
||
|
|
still process successfully and leave the field value as-is. In such a case, `target_field` will
|
||
|
|
still be updated with the unconverted field value.
