User Feedback Requested : Increment an property that doesnt exist

[sharan779]

Do you think Increment op should be a blind increment operator, meaning that the user might want to increment a property that might not even exist.

In this case, would you vote for having a default value of 0 or an extra optional parameter "ifNotExists" ?

Let us know your comments ?

My opinion on this: Keep it simple!

• No optional parameter
• If the property does not exist, it is initialized with 0 and incremented from there.

This should be just fine for most use cases. Anything more complicated (init value != 0; require already existing property) could be done with conditional patches.

I agree with @WWeichselberger and there is similar functionality for MongoDB: https://docs.mongodb.com/manual/reference/operator/update/inc/

+1 for the Keep it Simple, and Keep it familiar to other database systems where we can already do this.
