I have a streaming pipeline where one of my columns is a Map<String, String> I would like to add a new value to this map, but there does not seem to be an expression that accomplishes this. Am I missing something?

Hi @dherls, we don’t have an expression / transform that supports exactly this.

A workaround may involve exploding your map, and then re-grouping with added key/value pairs.

Is this an expression you’d like to see supported? We can add it as a feature request.

Yes I think add/remove/update values in maps would be greatly appreciated expressions
