| Maximum Message Size (KB) | Maximum size of each event batch sent to Azure Event Hubs, in KB.                                                                                                                      | Yes          |
| Combine Messages          | Combine multiple messages into a single JSON array to reduce message count.                                                                                                            | Yes          |

| 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 configurations

| **Field**                     | **Details**                                                                                                                                                                                          | **Required** |
| ----------------------------- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | ------------ |
| Persistent storage            | If enabled, messages in the outbound queue are stored on disk. If there are interruptions in connection or power loss, messages are retained and eventually sent when the connection is restored.    | No           |
| Persistent storage size limit | Set the size limit for storing persisted data in GB.                                                                                                                                                 | No           |
| Queue mode                    | Select the sequence of data transfer: `FIFO` or `LIFO`. Selecting `FIFO` (First In First Out) sends the earliest message first. Selecting `LIFO` (Last In First Out) sends the latest message first. | No           |
