Platform Events have changed the manner in which Salesforce organizations integrate real-time data and event-driven architectures. Nevertheless, most IT administrators subconsciously commit the Platform Event Trap or other pitfalls that are likely to derail their implementations.
The Platform Event Trap is a collection of errors that may cause possible system outages, loss of data, and other unforeseen production problems. As an IT administrator, you need to know these traps and prevent them before they affect your organization to achieve better reliability in Salesforce operations.
In this article, we will provide you with clear and practical step-by-step measures to ensure you avoid Platform Event Traps. You will learn how to identify early warning signs of a problem, best practices, and create powerful event-driven solutions that have the capacity to expand as your business requirements expand.
What is Platform Event Trap
A Platform Event Trap is a situation where Salesforce Firms take Salesforce Platform Events on board without configuration of the asynchronous properties and limitations. It is commonly viewed as a system failure, data inconsistency, or even a choke following installation.
The name Platform Event Trap is used to refer to several errors that occurred when using Platform Events:
Synchronous flows with Platform Events.
Failure to comply with the ordering and delivery guarantees of events.
Ignoring the restrictions and volume limits of the governor.
Limited environment testing only.
Failure to set up security appropriately.
The Platform Event Trap is especially perilous in that its early versions fail in a material sense when they are applied in the real world. Troubles occur only once production volumes, complicated integration environments, or edge cases have been encountered that were not originally considered in the testing environment.
Common Typical Mistakes
1. Excessive use of Platform Events to Synchronous Use Cases.
Most IT admins are attempting to apply the Platform Events as a means of immediate UI response or real-time user experience. Nonetheless, using this technique, Platform Events lead to a Platform Event Trap as they are asynchronous events by nature.
Imagine that the users are anticipating performing actions and getting instant visual feedback. The Platform Events approach in that case cannot be sure that processing will happen immediately. Depending upon the loads in the system, the event can take between milliseconds and a few seconds to execute.
Solution: Platform Events must be used by any background processes, system integrations, or workflows that do not require any timely user feedback. Synchronous operations should be selected with Lightning Web Components, Apex triggers, or Flow.
2. Disregard Event Ordering and Delivery Guarantees.
Salesforce states that Platform Events are not required to be returned in the sequence in which they were received. And in the event of system retries or network issues, one event can be sent out more than once.
Platform Event Trap surprises a lot of administrators when they build workflows with the assumption that they are done in sequence. Out-of-order events may cause the failure of critical business processes; processes may duplicate data.
Implementation strategy:
Write idempotent design event handlers that do not have issues with duplicate events.
Track the processing event status with unique identifiers.
Design Custom Logic Where It Is Essential to Have Strict Order.
Don’t think of Volume Limits or Governor Limits.
Best Practices to prevent the platform event trap.
1. Asynchronous, Decoupled Processing Design.
Rather than matching the asynchronous character of the Platform Events, design them to accept it. This principle can help to prevent most issues of Platform Event Trap. The common key guidelines are:
Separate business logic validation from event publishing.
Develop subscribers that are robust to processing delays.
Put in place a powerful error management and retries.
Take advantage of the process tracking that has been in place.
2. Apply High-Volume Platform Events
Standard Platform Events might not be adequate where an organization has to handle thousands of events in a day. High-Volume Platform Events (HVPE) have higher throughput and varying delivery promises.
When to choose HVPE:
Handling over 100,000 transactions a day.
Interoperability with high-transacting systems.
IoT devices communication control.
Scale analytics in real time.
3. Develop Idempotent Subscriber Logic.
Idempotent processing makes sure that the result of the same event is the same, though such an event may be consumed multiple times. This method will prevent most Platform Event Trap situations.
Ways to achieve this:
Deduplication: use event IDs.
Check the processing status before business rules.
Design database operations to be able to deal safely with duplicates.
Maintain processing logs to be seen and debugged.
4. Strategically Keep Track of Limits and Event Intake.
Periodic check-ups will identify and correct problems before they can impact production systems, thus preventing the risk of collapsing into the Platform Event Trap.
It is important to remember that the Platform Event implementations have to evolve with your business needs. Regular check-ups of your event architecture, monitors of monitoring data, and performance metrics allow you to timely identify improvement opportunities.
Frequently Asked Questions (FAQs)
1. So what is a Platform Event Trap in Salesforce?
A Platform Event Trap is a description of typical issues that lead Salesforce Platform Events to fail or, unexpectedly, result in unstable production. The issues may be due to misconceptions about their asynchronous character, fat fingers on delivery guarantee, and going above governor limits, which may break down. They are in development but not production.
2. What can I do to avoid my Platform Events processing the same event more than once?
Assign an event processing an identifier that is unique and should be forwarded to event subscribers. Log processed events. Check the log of the duplicates before executing the business logic, and in database handling, consider the options of dealing with duplicates.
3. Are Platform Events a correct delivery order?
Salesforce Platform Events does not currently provide a delivery sequence due to a combination of different processing systems and basic network latency. Your client code inviolability requires the use of custom logic, like timestamps or sequence numbers.
