```

Find matches across the existing and incremental frames and return a new frame with a column containing a unique ID per match group.
+ `existingframe` — An existing frame which has been assigned a matching ID for each group. Required.
+ `incrementalframe` — An incremental frame used to find matches against the existing frame. Required.
+ `transformId` — A unique ID associated with the FindIncrementalMatches transform to apply on the input frames. Required.
+ `transformationContext` — Identifier for this `DynamicFrame`. The `transformationContext` is used as a key for the job bookmark state that is persisted across runs. Optional.
+ `callSite` — Used to provide context information for error reporting. These values are automatically set when calling from Python. Optional.
+ `stageThreshold` — The maximum number of error records allowed from the computation of this `DynamicFrame` before throwing an exception, excluding records present in the previous `DynamicFrame`. Optional. The default is zero.
+ `totalThreshold` — The maximum number of total errors records before an exception is thrown, including those from previous frames. Optional. The default is zero.
+ `enforcedMatches` — The frame for enforced matches. Optional. The default is `null`.
+ `computeMatchConfidenceScores` — A Boolean value indicating whether to compute a confidence score for each group of matching records. Optional. The default is false.

Returns a new dynamic frame with a unique identifier assigned to each group of matching records.
