Information Server QualityStage Match error: "Block overflow limit of 100000 exceeds the maximum allowed value".
If poor blocking variables are defined in QualityStage match specification step or the user overrides the default Match Designer option: "Enter Overflow Value(s)", then the following error may occur:
"Block overflow limit of <Enter Overflow Value> exceeds the maximum allowed value of <limit>"
As a result, too many like records are blocked (grouped) together to be compared in the matching process. Like records indicates having the same data attributes within 1 field.
Resolving the problem
To resolve the over flow blocking error the following two design changes are recommended:
- Do not edit the default "Enter Overflow Value(s)" in the Match Designer interface. This value determines the maximum number of records that can be combined into one set.
- Ensure the fields used in the blocking logic do not have a lot of default values present. An example of such conditions are, all blanks or default value such as "00000","1111"...
