Use the EventFlow Editor's Parameters tab to define module parameters and their default values for the current EventFlow module. You can reference module parameters in expressions in any operator or adapter in the containing module. You can set values for module parameters in a number of ways. This allows you to reuse the same application module in different module references, with different parameter values. For details on module parameters see Parameter Overview and Using Module Parameters.
In StreamSQL programs, module parameters are declared with the CREATE PARAMETERS statement.
