 | Event serialization format | The serialization format for output data. JSON, CSV, and Avro are supported. |
 | Encoding | For CSV and JSON, UTF-8 is the only supported encoding format at this time. |
 | Delimiter | Applicable only for CSV serialization. Stream Analytics supports a number of common delimiters for serializing data in CSV format. Supported values are comma, semicolon, space, tab, and vertical bar. |
-| Format | Applicable only for JSON serialization. **Line separated** specifies that the output is formatted by having each JSON object separated by a new line. **Array** specifies that the output is formatted as an array of JSON objects. This array is closed only when the job stops or Stream Analytics has moved on to the next time window. In general, it's preferable to use line-separated JSON, because it doesn't require any special handling while the output file is still being written to. |
