| Name                      | Connector name                                                                                                                                                                                        | Yes          |
| Connection string         | Configuration string                                                                                                                                                                                  | Yes          |
| Maximum message size      | The maximum message size for an individual event (message) in Azure Event Hubs is 256 KB.                                                                                                             | Yes          |
| Parallel connections unit | Impose a strict limit on the maximum number of simultaneous connections or clients that can be established with an Event Hub.                                                                         | Yes          |
| Combine messages          | Message or event combination refers to the procedure of consolidating several separate messages or events into one unified message or event.                                                          | No           |
| Throttling limit          | Set a limit on the number of outbound messages per second. If sending data to a server that has restrictions on the rate of incoming messages, this ensures that no messages are lost.                | No           |
| Persistent storage        | If enabled, messages in the outbound queue are stored on disk. If there are interruptions in connection or power loss, messages will be retained and eventually sent when the connection is restored. | No           |
| Queue mode                | Select the sequence of data transfer: FIFO or LIFO. Selecting FIFO (First In First Out) will send the earliest message first. Selecting LIFO (Last In First Out) will send the latest message first.  | No           |
