Naming Conventions

Solution and stream names must be unique. When you duplicate a stream, '(Copy)' will be added to the end of the name to show it's a duplicate. Stream names can be up to 63 characters long, and you can rename them by clicking on the name itself in the stream view.

Note!
Duplicating a stream with a 63-character name will cause a 'bad request' error.

 

Function names must also be unique - when they’re duplicated within a stream they will be assigned a unique name with a copy number in parenthesis, for example, if the Count function is used multiple times, the consecutive functions are named Count (1), Count (2), and so on). Function names can be up to 30 characters long and can be edited by clicking on the name itself.

Accepted characters in name fields

The following characters are accepted in Usage Engine’s name fields.

  • Alphanumeric (a-z, A-Z, 0-9)

  • Space ( [space] )

  • Dash ( - )

  • Underscore ( _ )

  • Parenthesis ( () )

  • Period ( . )

 

Note!

The order of columns in a CSV file may not always match what you set in a function. For example, in a Map processor or Amazon S3 forwarder, if your headers include both numbers and letters, Usage Engine will place numeric headers first, followed by alphabetical ones.
