Pierre Villard commented on NIFI-7141:
--------------------------------------
If renaming the field is an option for you, you could use ReplaceText with some
regular expressions to prepend a letter to each numerical field name. Something
like:
{code:java}
Search value: "([0-9]+)":
{code}
{code:java}
Replacement value: "a$1":
{code}
Will close this JIRA with "Information provided" status. Feel free to reopen if
needed.

> Hi
> We have some incoming data that where the type is map. Problem is that key is
> int and not string which cause the map to have invalid data.
> Can Nifi add support for other data types for map keys as well?
> I have attached dummy example flow for example.
> If there is any good workaround that would be good start.
