from() function

from() queries data from an InfluxDB data source.

It returns a stream of tables from the specified bucket. Each unique series is contained within its own table. Each record in the table represents a single point in the series.

Query remote InfluxDB data sources

Use from() to query data from remote InfluxDB OSS 1.7+, InfluxDB Enterprise 1.9+, and InfluxDB Cloud. To query remote InfluxDB sources, include the host, token, and org (or orgID) parameters.

from() does not require a package import

from() is part of the influxdata/influxdb package, but is part of the Flux prelude and does not require an import statement or package namespace.
