How can the serialized size of EventData be determined for batching?

Question

In the documentation for the Azure EventHubClient there are two methods for sending a batch of data each of them has the remark below and will throw a MessageSizeExceededExc

Answer 1

----Updating after the Nuget Update---- Here's the EventData property - SerializedSizeInBytes that we introduced in our recent SDK iteration - which addresses this specific problem - available in all sdk nugets above 2.6 .

---Update after EventDataBatch utility---

use EventDataBatch.TryAdd(EventData) API to construct the batch. When the EventData cannot fit into the batch - this API will return false. Stop adding more events & then use the sender (EventHubClient or PartitionSender) to send the EventDataBatch.

following considerations motivated us to design EventDataBatch API:

• Help developers using our Client API - to deal with size of batch of EventData
• Abstract out region-wide/SKU-based MaximumMessageSize configuration: EventHubs service across the world could have different Max EventData sizes - across different EventHub regions and different SKUs of EventHub. We wanted to expose a uniform way for developers to construct maximum message size for any given environment. So, when EventDataBatch is initialized using eventHubClient.createBatch() API - the client negotiates batchSize with EventHubs Service and returns the EventDataBatch instance which can construct the correct size!

HTH! Sree
