+The `clientRetryOptions` are used to retry operations between the Functions host and Event Hubs (such as fetching events and sending events).  Please refer to guidance on [Azure Functions error handling and retries](../articles/azure-functions/functions-bindings-error-pages.md#retries) for information on applying retry policies to individual functions.
