Introduction

In the world of Salesforce, Platform Events play a crucial role in enabling real-time communication between external systems and Salesforce. With the introduction of High Volume Platform Events in Spring '19, developers can now handle a large volume of events without any limitations. However, converting an existing Standard Volume Event to a High Volume Event can be a challenging task. In this article, we will guide you through the process of converting a Standard Volume Event into a High Volume Platform Event.

Understanding Standard Volume Events and High Volume Events

Before we dive into the conversion process, let's understand the difference between Standard Volume Events and High Volume Events.

Standard Volume Events

High Volume Events

High Volume Events, on the other hand, are designed to handle a large volume of events without any limitations. They are suitable for large-scale applications that require real-time communication between external systems and Salesforce. High Volume Events have the following benefits:

Unlimited events per hour
Unlimited subscribers per event
Unlimited event payload size
