IBM Streams 4.2.1
Config clause
The config clause specifies hints and directives that influence how the compiler builds this operator invocation, or how the runtime system executes it.
The config clause in an operator invocation applies to the invoked primitive operator or, in the case of a composite operator, to all operators in the graph clause individually. You describe the rules for which config applies when there are ambiguities in the config clause on the operator definition.
Tip: Embedded config clauses are
useful during testing and development, but if you want your code to
be reused on different infrastructure, avoid hard-wiring anything
that is specific to your local infrastructure.
