How to increase message limit size of azure event hub from 1 MB to send 4 MB?

I have a requirement of sending 1,00,000 batch of records per second. What i got after experimenting is azure event hub has limit of 10,00,000 events in bytes. My each record is of 145 bytes and total records i have to send are 1,00,000 as i already mentioned above. So, mathematically, 145 * 1,00,000 = 14500000 bytes of data i want to send per second.

Can somebody help me with this ?

Now, to send this data i am using azure event hub SDK and using following method i am trying to send data : await eventHubClient.SendAsync(ed); (ed is the object of EventData which has records in bytes UTf 8 format.)

But, when i am running the code and executing the above line (SendAsync () ) i am getting the following error :

$exception  
{Microsoft.Azure.EventHubs.MessageSizeExceededException: The received message (delivery-id:0, size:3922220 bytes) exceeds the limit (1046528 bytes) currently allowed on the link.

You can not change it. The max size 1M is by design, you can consider reduce the size of your message.

You can take a look at reference here and here.
