The `increase()` function calculates the cumulative sum of **non-negative** differences
between subsequent values.
A main use case is tracking changes in counter values which may wrap over time
when they hit a threshold or are reset.
In the case of a wrap/reset, we can assume that the absolute delta between two
points will be at least their non-negative difference.

```js
increase(columns: ["_value"])
```

## Parameters

### columns {data-type="array of strings"}
Columns to use in the operation.
Default is `["_value"]`.

### tables {data-type="stream of tables"}
Input data.
Default is piped-forward data ([`<-`](/flux/v0.x/spec/expressions/#pipe-expressions)).

## Output tables
For each input table with `n` rows, `increase()` outputs a table with `n - 1` rows.

## Examples

```js
import "sampledata"

sampledata.int()
