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.
