array.from() function
The array.from() function is experimental and subject to change at any time.
By using this function, you accept the risks of experimental functions.
The experimental array.from() function constructs a table from an array of records.
Each record in the array is converted into an output row or record.
All records must have the same keys and data types.
Function type: Input
import "experimental/array"
array.from(rows: [
{_time: 2020-01-01T00:00:00Z, _field: "exampleField", _value: 3, foo: "bar"},
{_time: 2020-01-01T00:01:00Z, _field: "exampleField", _value: 4, foo: "bar"},
{_time: 2020-01-01T00:02:00Z, _field: "exampleField", _value: 1, foo: "bar"}
])
Parameters
rows
Array of records to construct a table with.
Data type: Array of records
Examples
Build an arbitrary table
import "experimental/array"
rows = [
{foo: "bar", baz: 21.2}
{foo: "bar", baz: 23.8}
]
array.from(rows: rows)
Union custom rows with query results
import "influxdata/influxdb/v1"
import "experimental/array"
tags = v1.tagValues(
bucket: "example-bucket",
tag: "host"
)
wildcard_tag = array.from(rows: [{_value: "*"}])
union(tables: [tags, wildcard_tag])
