FindIncrementalMatches class
Identifies matching records in the existing and incremental DynamicFrame and creates a new DynamicFrame with a unique identifier assigned to each group of matching records.
To import:
from awsglueml.transforms import FindIncrementalMatches
Methods
apply(existingFrame, incrementalFrame, transformId, transformation_ctx = "", info = "", stageThreshold = 0, totalThreshold = 0, enforcedMatches = none, computeMatchConfidenceScores = 0)
Identifies matching records in the input DynamicFrame and creates a new DynamicFrame with a unique identifier assigned to each group of matching records.
existingFrame– The existing and pre-matchedDynamicFrameto apply the FindIncrementalMatches transform. Required.incrementalFrame– The incrementalDynamicFrameto apply the FindIncrementalMatches transform to match against theexistingFrame. Required.transformId– The unique ID associated with the FindIncrementalMatches transform to apply on records in theDynamicFrames. Required.transformation_ctx– A unique string that is used to identify stats/state information. Optional.info– A string to be associated with errors in the transformation. Optional.stageThreshold– The maximum number of errors that can occur in the transformation before it errors out. Optional. The default is zero.totalThreshold– The maximum number of errors that can occur overall before processing errors out. Optional. The default is zero.enforcedMatches– TheDynamicFrameused to enforce matches. Optional. The default is None.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 DynamicFrame with a unique identifier assigned to each group of matching records.
