Dynamic Match Analysis Threshold

Dynamic Match Analysis Threshold

During the match process, dynamic match analysis determines whether the match process will take an unacceptably long period of time.
This threshold value specifies the maximum acceptable number of comparisons.
To enable the dynamic match threshold, specify a non-zero value. Enable this feature if you have data that is very similar (with high concentrations of matches) to reduce the amount of work expended for a hot spot in your data. A hotspot is a group of records representing overmatched data—a large intersection of matches. If Dynamic Match Analysis Threshold is enabled, then records that produce more than the specified number of potential match candidates will be skipped during the match process. By default, this option is zero (disabled).
Before conducting a match on a given search range,
Informatica MDM Hub
calculates the number of search records (records being searched for matches), and multiplies it by the number of file records (the number of records returned from the match key table that need to be compared). If the result is greater than the specified Dynamic Match Analysis Threshold, then no comparisons are performed on that range of data, and the range is noted in the application server log for further investigation.
