elapsed() function

elapsed() returns the time between subsequent records.

For each input table, elapsed() returns the same table without the first row (because there is no previous time to derive the elapsed time from) and an additional column containing the elapsed time.

Function type signature
(<-tables: stream[A], ?columnName: string, ?timeColumn: string, ?unit: duration) => stream[B] where A: Record, B: Record

For more information, see Function type signatures.



Unit of time used in the calculation. Default is 1s.


Column to use to compute the elapsed time. Default is _time.


Column to store elapsed times in. Default is elapsed.


Input data. Default is piped-forward data (<-).


Calculate the time between points in seconds

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.
