This node filters the traces with certain frequency from an event log. It has two strategies to filter. One is on trace variant. Trace variant is a collection of traces with the same event classes sequence. If the size of trace variant meets the condition, the trace collection will be added to the filtered event log; Else, the trace collection is disposed. The other filter type is on the whole event log. The filter criteria is applied to the sum of trace variant. Firstly, the traces in event log is sorted according to trace variant frequency in the descending order. For example, given the threshold 0.8, and isKeep = true, the trace variants with higher frequency are summed to meet 0.8. Their traces will be added to the generated event log.
