`Combine` | Identifies related events in different tracks and creates an output track where the information from both tracks is combined into a single output record.
`CombineWithLast` | Combines each record in one track with the most recent record from another track.
`Deduplicate` | Removes duplicate records by discarding identical records produced within a specific time interval of a record. You can specify the conditions to use to judge two records as being identical.
