query.inBucket() function

query.inBucket() is experimental and subject to change at any time.

query.inBucket() queries data from a specified InfluxDB bucket within given time bounds, filters data by measurement, field, and optional predicate expressions.

Parameters

bucket

(Required) InfluxDB bucket name.

measurement

(Required) InfluxDB measurement name to filter by.

start

(Required) Earliest time to include in results.

Results include points that match the specified start time. Use a relative duration, absolute time, or integer (Unix timestamp in seconds). For example, -1h, 2019-08-28T22:00:00Z, or 1567029600. Durations are relative to now().

stop

Latest time to include in results. Default is now().

Results exclude points that match the specified stop time. Use a relative duration, absolute time, or integer (Unix timestamp in seconds).For example, -1h, 2019-08-28T22:00:00Z, or 1567029600. Durations are relative to now().

fields

Fields to filter by. Default is [].

predicate

Predicate function that evaluates column values and returns true or false. Default is (r) => true.

Records (r) are passed to the function. Those that evaluate to true are included in the output tables. Records that evaluate to null or false are not included in the output tables.

Examples

Query specific fields in a measurement from InfluxDB

import "experimental/query"

query.inBucket(
    bucket: "example-buckt",
    start: -1h,
    measurement: "mem",
    fields: ["field1", "field2"],
    predicate: (r) => r.host == "host1",
)

The future of Flux

Flux is going into maintenance mode. You can continue using it as you currently are without any changes to your code.

Flux is going into maintenance mode and will not be supported in InfluxDB 3.0. This was a decision based on the broad demand for SQL and the continued growth and adoption of InfluxQL. We are continuing to support Flux for users in 1.x and 2.x so you can continue using it with no changes to your code. If you are interested in transitioning to InfluxDB 3.0 and want to future-proof your code, we suggest using InfluxQL.
