When naming solutions and streams ensure that unique names are used. The maximum length of a Solution name and a Function name is limited to 30 characters, and the maximum length of the Stream name is limited to 63 characters. When a function is used multiple times in a stream, each function node receives a unique name by appending copy numbers to each consecutive node (for example, if the Count function is used multiple times, the consecutive functions are named as Count (1), Count (2), and so on).
Note!
When a user tries to duplicate a stream with a maximum number of characters in its name, that is 63, it results in a "bad request". If the stream name does not have the maximum characters when it is duplicated, the duplicated stream name is appended with "(Copy1)".
Character restrictions are applicable to user input fields in . The character restrictions in
are applicable to account names, solution names, stream names, and node or function names. You can only use the following characters when naming:
Alphanumeric (a-z,A-Z, 0-9)
- Space
Dash ( - )
Underscore ( _ )
- Round brackets ( () )
Period ( . )
Note!
The order that you determine in a function for a CSV file is not guaranteed. For example, in a Map processor or Amazon S3 forwarder, if you have headers that are a mixture of numeric and alphabetical headers, orders the numeric headings followed by alphabetical headers.
