Key Pattern

The key pattern meaning depends on the Cache Scope.

If the Cache Scope is Flow Variable, the pattern is a regular expression pattern (regex). If the scope is Cache, the key pattern is a glob style pattern. When the pattern is defined, the node can be a 1st node and the input data is not required. If the node is not a 1st node or the data exist on the node input terminal, the data is ignored. Matched keys in a format defined with Data Format property is sent to the Matched terminal. No data is sent to the Unmatched terminal. Consult online documentation for details about regex and glob style patterns.
