# Deduplicate Engine

A Deduplicate engine 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. This section describes the parameters that you can set in the configuration section for a Deduplicate ESP task.

Configuration Parameter | Description
--- | ---
Input | The track to deduplicate.
LuaScript | A Lua script that determines whether two records are considered identical.
MinTimeInterval | The minimum time between records. The engine discards duplicate records that occur within this time interval.
PredicateType | The conditions to use to determine whether two records are considered identical.
Type | The type of ESP engine to use. Set this parameter to `deduplicate`.

## Output Tracks

This engine produces a single output track, named `TaskName.Output`. The output track has the same format as the input track.
