It may happen that if you are experimenting with you flows and you use context storage you may find at one point that you have a lot of scrap data stored and you may want to just wipe all. With persistable context with caching enabled it is kind of pain.  
Here's a little helper for you.

`[{"id":"45862c08.b69d64","type":"inject","z":"64513f88.6f389","name":"GLOBAL CONTEXT - DISCARD ALL","topic":"","payload":"DISCARD","payloadType":"str","repeat":"","crontab":"","once":false,"onceDelay":0.1,"x":200,"y":120,"wires":[["b41ba9df.53b0a8"]]},{"id":"b41ba9df.53b0a8","type":"function","z":"64513f88.6f389","name":"DISCARD","func":"var keys = global.keys();\nfor(var i=0;i<keys.length;i++){\n global.set(keys[i]);\n}\nnode.warn(\"global context cleared!\");","outputs":1,"noerr":0,"x":440,"y":120,"wires":[[]]}]`

It wipes all so handle with care 🙂

Hi.  
Does this works for flow context?  
How would be?  
Thanks.

Have you tried to replace `global` with `flow` in function node?
