array.from() function

array.from() is experimental and subject to change at any time.

array.from() constructs a table from an array of records.

Deprecated

Experimental array.from() is deprecated in favor of array.from(). This function is available for backwards compatibility, but we recommend using the array package instead.

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 signature
(<-rows: [A]) => stream[A] where A: Record
For more information, see Function type signatures.

Parameters

rows

Array of records to construct a table with.

Examples

Build an arbitrary table

import "experimental/array"

rows = [{foo: "bar", baz: 21.2}, {foo: "bar", baz: 23.8}]

array.from(rows: rows)

View example output

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])
