Exam Question

An integration architect needs to build a solution that will be using the Streaming API, but the data loss should be minimized, even when the client re-connects every couple of days.

Which two types of Streaming API events should be considered? (Choose two.)

A. PushTopic Events
B. Change Data Capture Events
C. High Volume Platform Events
D. Generic Events

Correct Answer

B. Change Data Capture Events
C. High Volume Platform Events

Explanation 1

To minimize data loss when using the Streaming API, an integration architect should consider using PushTopic Events and High Volume Platform Events.

PushTopic events are used to subscribe to a streaming channel based on the criteria defined in a PushTopic. When a record is created or updated that matches the criteria of a PushTopic, the associated client receives a notification.

High Volume Platform Events are used to publish large numbers of events at high speed. They are designed for use cases that require high-speed processing of large numbers of events.

Explanation 2

To minimize data loss when using the Streaming API, an integration architect should consider using PushTopic events and Change Data Capture events.

PushTopic events are used to subscribe to a stream of data based on a query. They are used to deliver notifications to a client application when the data changes. PushTopic events are durable and can be stored for up to 24 hours.

Change Data Capture (CDC) events are used to capture changes in Salesforce records. CDC events are durable and can be stored for up to 72 hours.

Explanation 3

Streaming API supports four types of events that you can publish and subscribe to: PushTopic events, generic events, platform events, and Change Data Capture events. PushTopic events track field changes in Salesforce records and are tied to Salesforce records. Generic events contain arbitrary payloads that are not tied to Salesforce records. Platform events are custom events that you define in Salesforce and publish and subscribe to using a message bus. Change Data Capture events capture changes to Salesforce records and deliver them as events to external systems or other Salesforce orgs.

To minimize data loss, even when the client re-connects every couple of days, the integration architect needs to build a solution that will use the Streaming API events that have the longest replay retention window. The replay retention window is the time period for which the events are stored and available for replay. According to the documentation, the replay retention window for PushTopic events is 24 hours, for generic events is 72 hours, for platform events is 72 hours (or 24 hours for high volume platform events), and for Change Data Capture events is 72 hours (or 24 hours for high volume Change Data Capture events). Therefore, the two types of Streaming API events that have the longest replay retention window are B. Change Data Capture Events and C. High Volume Platform Events. These two types of events can be replayed up to 72 hours after they are generated.

Explanation 4

To minimize data loss when using the Streaming API, the integration architect should consider the following two types of Streaming API events:

Change Data Capture (CDC) Events: Change Data Capture is a feature in Salesforce that captures and propagates data changes in real-time. It allows you to receive near-real-time notifications of record changes in Salesforce. By subscribing to CDC events, the integration architect can ensure that any changes made to records are immediately captured and propagated to the client, minimizing data loss. CDC events provide a reliable way to receive updates when records are created, updated, deleted, or undeleted.
High Volume Platform Events: Platform events in Salesforce are used to deliver secure and scalable custom notifications within Salesforce or to external systems. High Volume Platform Events specifically cater to high-velocity event delivery scenarios, where thousands of events are generated per second. By leveraging High Volume Platform Events in the Streaming API, the integration architect can ensure that even if the client reconnects every couple of days, they won’t miss out on critical events. These events are designed to handle high data volumes and provide reliable event delivery.

A and C are the correct options: A. PushTopic Events and C. High Volume Platform Events.

PushTopic events are a legacy option that can also be considered for minimizing data loss in certain scenarios. They allow you to define a query and receive updates whenever records that match the query criteria are created, updated, deleted, or undeleted. However, they have some limitations compared to CDC events and High Volume Platform Events, such as a limited number of PushTopic queries per organization and less efficient performance when dealing with high data volumes. Therefore, while they can be considered, they are not as optimal for minimizing data loss in scenarios where clients reconnect every couple of days.

D. Generic Events are not a specific type of event in the Streaming API. Therefore, they are not relevant to this scenario.

In summary, the integration architect should primarily consider Change Data Capture (CDC) events and High Volume Platform Events when building a solution with the Streaming API to minimize data loss, especially when the client reconnects every couple of days.

Explanation 5

I am an expert in Salesforce Certified Integration Architect certification exam. Here is my answer to the below question and a detailed comprehensive explanation.

An integration architect needs to build a solution that will be using the Streaming API, but the data loss should be minimized, even when the client re-connects every couple of days. Which two types of Streaming API events should be considered? (Choose two.)

A. PushTopic Events
B. Change Data Capture Events
C. High Volume Platform Events
D. Generic Events

The correct answer is B and C.

Change Data Capture Events are events that capture changes to Salesforce records and deliver them to external systems in near real-time. They are suitable for scenarios where data loss should be minimized, as they provide reliable message delivery and support replaying events within a 72-hour window.

High Volume Platform Events are events that are defined in Salesforce and published by using Apex or APIs. They are suitable for scenarios where a large number of messages need to be delivered quickly and reliably, as they support publishing up to 250,000 events per second and replaying events within a 24-hour window.

PushTopic Events are events that are based on SOQL queries that define the data changes to be notified of. They are not suitable for scenarios where data loss should be minimized, as they do not support replaying events and have a lower limit of publishing up to 2,000 events per second.

Generic Events are events that are defined outside of Salesforce and sent to Salesforce by using an API. They are not suitable for scenarios where data loss should be minimized, as they do not support replaying events and have a lower limit of publishing up to 5,000 events per second.

Explanation 6

The correct answers are:

PushTopic Events
Change Data Capture Events

PushTopic Events are a type of Streaming API event that is delivered to subscribers based on a subscription to a specific topic. PushTopic Events are persistent, which means that they are stored in the Salesforce database and can be retrieved even if the client disconnects.

Change Data Capture Events are a type of Streaming API event that is generated when data is changed in Salesforce. Change Data Capture Events are also persistent, which means that they are stored in the Salesforce database and can be retrieved even if the client disconnects.

High Volume Platform Events are a type of Streaming API event that is generated when a large number of events are generated in a short period of time. High Volume Platform Events are not persistent, which means that they are not stored in the Salesforce database and cannot be retrieved if the client disconnects.

Generic Events are a type of Streaming API event that is generated for a variety of purposes. Generic Events are not persistent, which means that they are not stored in the Salesforce database and cannot be retrieved if the client disconnects.

Therefore, the two types of Streaming API events that should be considered are PushTopic Events and Change Data Capture Events. These events are persistent, which means that they can be retrieved even if the client disconnects. This is important for the integration architect’s solution, as the client will be reconnecting every couple of days.

Explanation 7

The correct answers are B and C.

Change Data Capture (CDC) events are a type of Streaming API event that are used to track changes to records in Salesforce. CDC events are delivered in near real-time, and they can be used to keep a client application up-to-date with the latest changes to Salesforce data.

High Volume Platform Events (HVPE) are a type of Streaming API event that are used to publish large amounts of data to a large number of subscribers. HVPE events are delivered in batches, and they can be used to send data to a client application that needs to be updated on a regular basis.

PushTopic Events and Generic Events are not suitable for this use case because they are not designed to minimize data loss. PushTopic Events are used to send notifications to subscribers, and Generic Events are used to publish data to a specific channel.

Therefore, the integration architect should consider using CDC events and HVPE events to build a solution that will minimize data loss, even when the client re-connects every couple of days.

Explanation 8

The two types of Streaming API events that should be considered are PushTopic Events and Change Data Capture Events.

PushTopic Events are sent to subscribers when records are created, updated, or deleted in Salesforce. These events are delivered in real time, and they can be used to trigger actions in other systems. For example, a PushTopic Event could be used to notify a marketing automation system when a new lead is created in Salesforce.

Change Data Capture Events are also sent to subscribers when records are created, updated, or deleted in Salesforce. However, these events are not delivered in real time. Instead, they are delivered in batches, and they can be used to keep track of changes to data over time. For example, a Change Data Capture Event could be used to keep track of changes to customer contact information.

High Volume Platform Events are used to publish large amounts of data to subscribers. These events are delivered in real time, and they can be used to trigger actions in other systems. For example, a High Volume Platform Event could be used to publish stock market data to a financial analysis system.

Generic Events are used to publish custom data to subscribers. These events are delivered in real time, and they can be used to trigger actions in other systems. For example, a Generic Event could be used to publish a custom notification to a mobile app.

In this case, the integration architect needs to build a solution that will be using the Streaming API, but the data loss should be minimized, even when the client re-connects every couple of days. This means that the solution needs to be able to keep track of changes to data over time, even if the client is not connected to the Streaming API at all times.

PushTopic Events and Change Data Capture Events are both suitable for this purpose. PushTopic Events are delivered in real time, so they can be used to keep track of changes to data as they happen. Change Data Capture Events are not delivered in real time, but they can be used to keep track of changes to data over time.

High Volume Platform Events and Generic Events are not suitable for this purpose. High Volume Platform Events are used to publish large amounts of data, and Generic Events are used to publish custom data. Neither of these types of events are suitable for keeping track of changes to data over time.

Therefore, the two types of Streaming API events that should be considered are PushTopic Events and Change Data Capture Events.
