If you have relatively static tables, then you can simplySet(aVariable, yourDataSourceOrFilter). Hence, OData requests via the connector were slower than that via MicrosoftDataverse connector. The Variable name I have given ProductDetails and store the Table records. Multi-table lookups (also sometimes known as Polymorphic Lookups) allow the creation of a lookup in one table that looks up records in multiple other tables at once. But, while they liked the concept, they and their clients, struggled to get past the fact that they could purchase a few SharePoint licenses (for admins) and then let everyone else in for free as Guest users.

The variable name is StudentMarkSheet. Microsoft Dataverse based apps support complex filtering via views, which can include multiple tables. Within a controlled environment, the performance benchmark has proved that the performance of OData requests against SharePoint list were highly related to the number of columns in the list and the number of rows retrieving limited by Data Low Limits. SharePoint connector pipelines to SharePoint list(s). When you use the MicrosoftDataverse connector to access a MicrosoftDataverse environment, data requests would go to the environment instance directly, without passing through API management. MicrosoftDataverse has enabled by default so that when you create a new canvas app connecting to your MicrosoftDataverse instance, data requests from your app will execute through MicrosoftDataverse onto your MicrosoftDataverse instance. Once on-premises data gateway is configured, Power Apps canvas app can manage data with various on-premises data sources such as SQL, Oracle, SharePoint on on-premises networks. For more information, see the delegation overview. Delegating the workload to the server would be recommended too. They are still valid for other data sources on-premises.

The Mobile Details contains a sub table. For a collection, the entire record must match. By doing this way, you can let the app start fast and other steps can be continued along with app launching. Concisely, performance overhead could be happening at any of the layers from client, APIM, connector, on-premises data gateway and backend data sources. The OnStart event runs when the application is loading and having lots of data called in the OnStart command will slow down the load of the app. Thanks anyway.

Well, robbing a bank is not a bad choice if that is your only option. Although Power Apps has already put in place the Content Delivery Network (CDN) delivering necessary contents of the app from the nearest CDN, data calls would still get the data from the backend data source which might be in different geographical locations. I have created a Table and stored the Product field value and inside the table I have created one more table and added some record value. Then, MicrosoftDataverse connector will interpret what columns been used in the app and only used columns in the app would be retrieved. Instead it returns a temporary table made of its arguments. For Group By I have added one more button.
