Numerical Filter (Siddhi)

---

Description

The Numerical Filter processor filters numerical values based on a given threshold. Therefore, it uses the lightweight CEP engine Siddhi by issuing a Siddhi query, e.g.

// filter query to filter out all events not satisfying the condition
from inputStreamName[numberField<10]
select *

---

Required input

The processor works with any input event that has one field containing a numerical value.

Configuration

Field

Specifies the field name where the filter operation should be applied on.

Operation

Specifies the filter operation that should be applied on the field.

Threshold value

Specifies the threshold value.

Output

The processor outputs the input event if it satisfies the filter expression.
