[jira] [Commented] (FLINK-14274) RuntimeContext can be get from FunctionContext
[ https://issues.apache.org/jira/browse/FLINK-14274?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel=16940768#comment-16940768 ] Jark Wu commented on FLINK-14274: - I agree with [~ykt836], we can definitely add more reasonable methods in FunctionContext, but state methods is not one of them. For example, adding methods for taskName and taskIndex and configurations make sense to me. > RuntimeContext can be get from FunctionContext > --- > > Key: FLINK-14274 > URL: https://issues.apache.org/jira/browse/FLINK-14274 > Project: Flink > Issue Type: Improvement > Components: Table SQL / API >Affects Versions: 1.9.0 >Reporter: hailong wang >Priority: Major > Fix For: 1.10.0 > > > Now, we can get metricGroup、cachedFile and jobParameter from functionContext > in UDF.

If you want to use other functions other than state in RuntimeContext, you can open other issues to describe what kind of methods you want and we can add them to the FunctionContext. I will close this for now, we can re-open it once needed. > RuntimeContext can be get from FunctionContext > --- > > Key: FLINK-14274 > URL: https://issues.apache.org/jira/browse/FLINK-14274 > Project: Flink > Issue Type: Improvement > Components: Table SQL / API >Affects Versions: 1.9.0 >Reporter: hailong wang >Priority: Major > Fix For: 1.10.0 > > > Now, we can get metricGroup、cachedFile and jobParameter from functionContext > in UDF.
