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.
