experimental.to() function
The experimental.to()
function is subject to change at any time. By using this function, you accept the risks of experimental functions.
The experimental.to()
function writes data to an InfluxDB v2.0 bucket, but in a different structure than the built-in to()
function.
*Function type: Output*
import "experimental"
experimental.to(
bucket: "my-bucket",
org: "my-org"
)
// OR
experimental.to(
bucketID: "1234567890",
orgID: "0987654321"
)
Expected data structure
Data structure expected by built-in to()
The built-in to()
function requires _time
, _measurement
, _field
, and _value
columns. The _field
column stores the field key and the _value
column stores the field value.
_time | _measurement | _field | _value |
---|---|---|---|
timestamp | measurement-name | field key | field value |
Data structure expected by experimental to()
experimental.to()
requires _time
and measurement
columns, but field keys and values are stored in single columns with the field key as the column name and the field value as the column value.
_time | _measurement | field_key |
---|---|---|
timestamp | measurement-name | field value |
If using the built-in from()
function, use pivot()
to transform data into the structure experimetnal.to()
expects. See the example below.
Parameters
bucket
The bucket to write data to. bucket
and bucketID
are mutually exclusive.
*Data type: String*
bucketID
The ID of the bucket to write data to. bucketID
and bucket
are mutually exclusive.
*Data type: String*
org
The organization name of the specified bucket
. Only required when writing to a different organization or a remote host. org
and orgID
are mutually exclusive.
*Data type: String*
orgID
The organization ID of the specified bucket
. Only required when writing to a different organization or a remote host. orgID
and org
are mutually exclusive.
*Data type: String*
Examples
Use pivot() to shape data for experimental.to()
import "experimental"
from(bucket: "example-bucket")
|> range(start: -1h)
|> pivot(
rowKey:["_time"],
columnKey: ["_field"],
valueColumn: "_value")
|> experimental.to(
bucket: "bucket-name",
org: "org-name"
)
