Hi, I would like to use accumulators with table /scalar functions. However, I am not able to figure out how to get the runtime context from inside of scalar function open method. Only thing i see is function context which can not provide the runtime context.
I tried using AbstractRichFunction.getRuntimeContext() <https://ci.apache.org/projects/flink/flink-docs-release-1.3/api/java/org/apache/flink/api/common/functions/AbstractRichFunction.html#getRuntimeContext--> . which I guess is not allowed from open of scalar or table functions. Any help will be appreciated. Thanks
