Understanding the Differences Between Client-driven and Server-driven Paging for Salesforce Connect

In the world of Salesforce Connect with OData adapters, paging plays a crucial role in managing large sets of data. It allows for efficient retrieval and display of data by breaking it down into manageable chunks. Two common approaches to paging are client-driven and server-driven paging. In this article, we will delve into these two methods, explore their differences, and understand when to use each approach. So, let's dive in!


What is Paging?


Client Server Paging Salesforce

Paging refers to the process of retrieving and displaying data in small portions or pages instead of fetching the entire dataset at once. It is particularly useful when dealing with large datasets to avoid performance issues and reduce network overhead. Paging ensures that only the required data is fetched from the server, enhancing the overall efficiency of data retrieval.


Client-driven Paging

In client-driven paging, the client application is responsible for managing the paging process. The client decides how many records to fetch and when to request additional pages. The client controls the pagination logic, making subsequent requests for the next set of records as needed.


To implement client-driven paging with Salesforce Connect and OData adapters, you need to configure the appropriate settings in your client application. The client sets the page size and determines when to retrieve the next page based on user interactions or predefined logic. This approach provides more flexibility to the client application but requires additional implementation effort.


Server-driven Paging

On the other hand, server-driven paging places the responsibility of paging on the server-side. In this approach, the server determines the page size and sends the data to the client in predefined chunks or pages. The server controls the pagination logic and returns only the requested page of data.


With Salesforce Connect and OData adapters, server-driven paging is the default behavior. The server handles the pagination automatically, and the client receives the data in a sequential manner without having to explicitly manage the paging process. This approach simplifies the implementation for the client application but may have limitations depending on the server's capabilities.


Differences Between Client-driven and Server-driven Paging

There are several key differences between client-driven and server-driven paging. Let's explore them:


  • Responsibility: In client-driven paging, the client application is responsible for managing the paging process, while in server-driven paging, the server handles the pagination logic.

  • Flexibility: Client-driven paging offers more flexibility as the client can control the page size and decide when to request the next page. Server-driven paging, on the other hand, follows a predefined page size and sequential data retrieval.

  • Implementation Effort: Client-driven paging requires additional implementation effort on the client application side to handle the pagination logic. Server-driven paging, being the default behavior, requires minimal client-side implementation.

  • Server Load: Client-driven paging can potentially impose a higher load on the server as it relies on multiple requests from the client for fetching data. Server-driven paging optimizes server load by sending only the requested page of data.


When to Use Client-driven Paging?

Client-driven paging is suitable when:


  • The client application requires more control over the paging process.

  • The client needs to implement custom pagination logic.

  • The server does not support server-driven paging.

  • Implementing client-driven paging allows the client application to tailor the pagination behavior according to specific requirements and user interactions.


When to Use Server-driven Paging?

Server-driven paging is recommended when:


  • The server supports server-driven paging.

  • The client application requires a simplified implementation without the need for custom pagination logic.

  • Performance and server load optimization are critical factors.

  • Server-driven paging offloads the burden of managing pagination from the client to the server, providing a streamlined approach to data retrieval.

Best Practices for Paging in Salesforce Connect with OData Adapters

To optimize the paging process in Salesforce Connect with OData adapters, consider the following best practices:


  • Page Size: Choose an optimal page size based on the nature of your data and network conditions. Smaller page sizes reduce the load on the server and improve response times.

  • Caching: Leverage caching mechanisms to store frequently accessed data pages on the client-side. This reduces the number of requests sent to the server, enhancing performance.

  • Pre-fetching: Implement pre-fetching techniques to retrieve subsequent pages in advance, minimizing latency and improving user experience.

  • Error Handling: Handle paging-related errors gracefully and provide appropriate feedback to users. Implement error handling mechanisms to ensure smooth data retrieval.

  • Monitoring and Tuning: Continuously monitor and tune the paging process to optimize performance and address any bottlenecks that may arise.

Conclusion

Understanding the differences between client-driven and server-driven paging is essential when working with Salesforce Connect and OData adapters. Both approaches have their strengths and considerations. Client-driven paging offers flexibility and customizability, while server-driven paging simplifies the implementation and optimizes server load. Choose the appropriate approach based on your requirements, server capabilities, and performance considerations to ensure efficient data retrieval and an enhanced user experience.
