Task options define specific information about a task.
They are set in a Flux script or in the InfluxDB user interface (UI).
The following task options are available:

- [name](#name)
- [every](#every)
- [cron](#cron)
- [offset](#offset)
- [concurrency](#concurrency)

{{% note %}}
`every` and `cron` are mutually exclusive, but at least one is required.
{{% /note %}}

## name
The name of the task. _**Required**_.

_**Data type:** String_

```js
option task = {
  name: "taskName",
  // ...
}
```

## every

The interval at which the task runs. This option also determines when the task first starts to run, depending on the specified time (in [duration literal](/{{< latest "flux" >}}/spec/lexical-elements/#duration-literals)).

_**Data type:** Duration_

```js
option task = {
  // ...
  every: 1h,
}
```

For example, if you save or schedule a task at 2:30 and run the task every hour (`1h`):

`option task = {name: "aggregation", every: 1h}`

The task first executes at 3:00pm, and subsequently every hour after that.

{{% note %}}
In the InfluxDB UI, the **Interval** field sets this option.
{{% /note %}}

## cron
The [cron expression](https://en.wikipedia.org/wiki/Cron#Overview) that
defines the schedule on which the task runs.
Cron scheduling is based on system time.

_**Data type:** String_

```js
option task = {
  // ...
  cron: "0 * * * *",
}
```

## offset

Delays the execution of the task but preserves the original time range.
For example, if a task is to run on the hour, a `10m` offset will delay it to 10
minutes after the hour, but all time ranges defined in the task are relative to
the specified execution time.
A common use case is offsetting execution to account for data that may arrive late.

_**Data type:** Duration_

```js
option task = {
  // ...
  offset: 10m,
}
```

## concurrency
The number task of executions that can run concurrently.
If the concurrency limit is reached, all subsequent executions are queued until
other running task executions complete.

_**Data type:** Integer_

```js
option task = {
  // ...
  concurrency: 2,
}
```
