> When calling functions through REST API it's not possible to pass a filter.
> The customer would like this ability, as the workaround proposed is
> suboptimal.
> An excerpt from from a John Blum’s email with more context:
> I can confirm that the GemFire Function Execution (DEV) REST API web service
> endpoint
> (https://github.com/apache/incubator-geode/blob/develop/gemfire-web-api/src/main/java/com/gemstone/gemfire/rest/internal/web/controllers/FunctionAccessController.java#L112-L245)
> [0] does not support passing filter information.
> As you can see from the execution
> (https://github.com/apache/incubator-geode/blob/develop/gemfire-web-api/src/main/java/com/gemstone/gemfire/rest/internal/web/controllers/FunctionAccessController.java#L203-L209)
> [1], there is no...
> Execution function = ...
> ...
> function.withFilter(set).withArgs(args).execute();
> That would require the Spring Web MVC, REST Controller endpoint (POST
> /gemfire-api/functions/
> {functionId}
> ) and handler method, execute(..), to take a Set<String>
> (https://github.com/apache/incubator-geode/blob/develop/gemfire-web-api/src/main/java/com/gemstone/gemfire/rest/internal/web/controllers/FunctionAccessController.java#L135-L141)
> [2] parameter for the filter, something like...
> public ResponseEntity<String> execute(..., @RequestParam(value = "filters",
> required = false) Set<String> filter, ...)
> { .. }
> Then the Function Execution would be...
> function.withFilter(filter).withArgs(args).execute();
> Simply passing the filter as part of the Function/Execution arguments will
> not result in GemFire routing the Function execution request based on the
> filter since the filter will be just part of the "arguments" (in the HTTP
> request message body) that are passed to the Function execution. I.e. the web
> service endpoint will not be able to distinguish the "filter" from the
> arguments and there all HTTP request message body contents as arguments to
> the Function.
