What are Salesforce Platform Events?

Platform Events in Salesforce provide a communication platform that facilitates real-time exchanges between distinct pieces of an application. This messaging infrastructure adopts a publish-subscribe approach, where one element emits an event, and any autonomous segments can subscribe to that event to acquire notification. This decoupled construction makes it possible for programmers to create robust and adaptable applications.  

Difference Between Traditional Apex Triggers and Platform Events

Key characteristics of Platform Events

Asynchronous Communication

Platform Events are used to facilitate asynchronous interactions between distinct components of an application. Instead of having to await an instantaneous response after liberating a petition, a unit can publish an event and progress with its operations. This is especially useful when rapid updates are necessary, such as with real-time dashboards or notifications.  

Decoupled Architecture

Platform Events decouple the sender and receiver of events. This means that the components producing events don't need to know who or what will consume those events. Similarly, components subscribing to events don't need to know where the events are coming from. This decoupling simplifies application design and maintenance.  

Event-Driven Paradigm

Facilitated by an event-driven paradigm, Platform Events are well-suited for creating real-time applications. Events can be representative of a great array of occurrences, from external data changes to user activity. This versatility provides builders with the ability to construct applications that respond to changes in the world around them quickly. Utilizing tools like the Lightning App Builder, developers can seamlessly integrate Platform Events into custom Lightning apps, enhancing user interfaces with real-time data and interactions.

Importance of Real-Time Applications in Salesforce

Real-time applications in Salesforce significantly enhance customer experience by providing instant access to up-to-date information, enabling timely responses and personalized interactions. They also boost operational efficiency by automating workflows and reducing delays in data processing, ensuring seamless business operations.

Examples of business scenarios requiring instant data updates include order processing systems that track inventory in real-time, notification services alerting users about critical events, and IoT integrations monitoring device statuses to trigger immediate actions.

Benefits of Real-Time Applications

• Faster Decision-Making: Immediate data availability allows businesses to make informed decisions quickly, responding effectively to market changes and customer needs.

• Enhanced Collaboration: Real-time updates keep teams synchronized, improving communication and coordination across departments and remote locations.

• Reduced Errors: Automated data synchronization minimizes manual entry mistakes and ensures consistent information across all systems, enhancing overall data accuracy.

Building Real-Time Applications with Platform Events : Salesforce

Now that we understand what Platform Events are, let's explore how they can be used to develop real-time applications.  

Real-Time Dashboards

One of the most common use cases for Platform Events is creating real-time dashboards. These dashboards can display critical business metrics, such as sales figures, customer support tickets, or website traffic, as they happen. By subscribing to relevant Platform Events, the dashboard components can update in real-time, providing decision-makers with up-to-the-minute information. 

For example, a sales team can use Platform Events to track incoming leads and opportunities. When a new lead is generated, an event is published, and the sales dashboard updates to reflect this change. This allows sales reps to respond promptly to new leads, improving their conversion rates. 

Instant Notifications

Platform Events are also an excellent tool for delivering instant notifications to users. Whether it's notifying a customer service agent about a new support ticket or alerting a field service technician about an urgent service request, Platform Events ensure that the right people are informed in real-time. 

By signing up for pertinent gatherings, users can be informed of such events through a variety of methods, such as emails, SMSs, or within-application notices. These messages can be tailored to provide greater clarity and pertinent data, permitting users to rapidly act upon essential situations. 

Data Synchronisation

In distributed systems, data synchronisation is a common challenge. Platform Events can help maintain data consistency across different systems and applications by broadcasting events when data changes occur. Subscribers can then update their local data stores, accordingly, ensuring that everyone has access to the latest information.  

For example, a company might use Salesforce app development to manage customer information and an external inventory management system to track product availability. When a product's stock level changes in the inventory system, it can publish an event that Salesforce subscribes to. Salesforce can then update its records to reflect the current stock status, ensuring that sales teams have accurate information when interacting with customers.  

IoT Integration

The Internet of Things (IoT) is all about connecting devices and sensors to the internet to collect and exchange data. Platform Events can play a crucial role in integrating IoT data into Salesforce and other business systems. IoT devices can publish events to indicate changes in sensor readings, equipment status, or environmental conditions.  

For instance, a smart building management system can use Platform Events to notify maintenance teams when a temperature sensor detects an anomaly. This proactive approach allows issues to be addressed before they escalate, improving operational efficiency and reducing downtime. 

Collaborative Workflows​

Real-time collaboration is essential for remote teams and distributed organisations. Platform Events can facilitate collaborative workflows by keeping team members updated on project progress and task assignments. Events can be triggered when tasks are assigned, completed, or delayed, ensuring that everyone is on the same page. 

Core Components of Salesforce Platform Events

Event Message Structure

Salesforce Platform Events consist of event messages that carry data in a structured format. Each event message includes standard and custom fields that define the payload, enabling relevant information to be transmitted. These fields are immutable once the event is published, ensuring data integrity throughout the event lifecycle.

Publishing Mechanisms

Platform Events can be published through multiple methods including Apex code, Process Builder, and Flow automation. Apex allows developers to programmatically publish events with fine control, while Process Builder and Flow offer declarative options for publishing events based on specific criteria or triggers. This flexibility supports diverse integration and automation scenarios. Additionally, Platform Events have an associated tab in Salesforce Setup where admins and developers can manage event definitions, view event schema details, and configure related settings.

Subscribing Mechanisms

Subscribers to Platform Events can include Apex triggers, external applications using the CometD protocol, and declarative tools like Flow. Apex triggers process incoming events within Salesforce, while external apps can listen for events in real-time via Salesforce APIs. This multi-channel subscription model enables seamless communication across systems.

Event Bus Architecture

The Salesforce event bus acts as the central messaging backbone, temporarily storing published events and delivering them to subscribers asynchronously. It supports the publish-subscribe model, decoupling event producers and event consumers to enhance scalability and flexibility. The event bus also manages event replay within a retention window, ensuring reliable event processing.Event Bus temporarily stores published event messages for up to 72 hours, allowing subscribers to retrieve missed events.

Step-by-Step Guide to Developing Real-Time Applications

Designing Event Messages

Start by defining the event message schema that outlines the structure and fields of the event. Ensure the event message includes all necessary data points for subscribers to act upon. Use platform event fields wisely to keep the messages efficient and meaningful. Proper design helps maintain clarity and scalability in your event-driven architecture.Platform Events can have custom fields, but they do not have page layouts and cannot be viewed in the Salesforce UI.

Publishing Platform Events

Publish platform events using Apex triggers, process builder, or Salesforce API based on your use case. Event producers send these events onto the event bus for consumption. Ensure publishing logic handles bulk operations and error scenarios gracefully. This step initiates the real-time flow of information across systems.Platform Events are immutable and cannot be updated once published.

Subscribing to Events

Event consumers subscribe to platform events through Apex triggers, flows, or external apps using the Salesforce API. Subscribers listen for incoming events on the event bus and execute corresponding business logic. Design subscriptions to handle event replay and possible gaps in event delivery to ensure reliability.

Testing and Debugging Event Flows

Test event publishing and subscription thoroughly using Salesforce developer tools and sandbox environments. Use debug logs to trace event processing and identify errors or performance bottlenecks. Simulate various event scenarios to validate system behavior under different conditions for robustness.

Monitoring Event Delivery and Failures

Monitor event delivery status and failures using Salesforce monitoring tools and dashboards. Track metrics such as event processing time, failed subscriptions, and replay IDs to detect gaps. Implement alerting mechanisms to respond quickly to issues and maintain system reliability.

Implementing Platform Events in Salesforce 

To implement Platform Events in Salesforce, you'll need to follow these steps:  

• Define the Event Schema: Start by defining the schema for your Platform Event. This schema determines the structure of the event and the data it can carry.  

• Create the Platform Event: Use Salesforce's setup tools to create the Platform Event object based on the schema you defined. This object will store the events and serve as the source of truth for event data. 

• Publish Events: To publish events, use Apex triggers or processes that run when specific conditions are met. These triggers or processes can be associated with standard objects, custom objects, or external systems.  

• Subscribe to Events: Subscribing to events is done through Salesforce triggers or external applications using Salesforce APIs. Subscribers can specify the events they want to receive and define the actions to take when events occur. 

• Handle Events: Once an event is received, the subscriber can process it, update records, trigger workflows, or send notifications, depending on the application's requirements.  

• Monitoring and Analytics: Salesforce provides monitoring tools and analytics to track event usage, troubleshoot issues, and gain insights into how events are impacting your application's performance. 

Best Practices for Platform Event Development 

When developing real-time applications with Platform Events, consider the following best practices:  

• Design for Scalability: Ensure that your event-driven architecture can scale to handle a large volume of events. Use batching and asynchronous processing where appropriate.  

• Error Handling: Implement robust error-handling mechanisms to deal with scenarios where events fail to publish or subscribe.  

• Event Versioning: Plan for event schema changes by versioning your events. This ensures backward compatibility when you need to make updates. 

• Security and Access Control: Apply proper security measures to restrict access to events and ensure that only authorised users and systems can publish and subscribe.  

• Logging and Monitoring: Implement comprehensive logging and monitoring to track event flows, troubleshoot issues, and proactively address performance bottlenecks.  

• Testing: Thoroughly test your event-driven application to validate that events are published and received correctly, and that the application behaves as expected under various conditions. 

• Documentation: Maintain clear documentation of your event schemas, publishing logic, and subscriber expectations to facilitate collaboration among developers and teams.
