The three actions that can be taken to minimize the performance impact of the Tempo report are:

• Limit the number of series values and categories in the report. This is because having too many series values and categories can make the report difficult to read and render, as well as increase the amount of data that needs to be transferred from the database to Appian. A good practice is to limit the number of series values to 10 or less, and the number of categories to 20 or less.
• Use local variables in your report interface to avoid redundant database queries. This is because local variables can store the results of database queries and reuse them in multiple places within the interface, reducing the number of times the database is accessed. A good practice is to use local variables for common filters, aggregations, or calculations that are used in multiple charts or grids.
• Perform aggregation in the database using a view prior to reading the data into Appian. This is because performing aggregation in the database can reduce the amount of data that needs to be transferred from the database to Appian, as well as leverage the database’s optimization capabilities. A good practice is to create a view in the database that performs the aggregation and then query that view using Appian. References: Report Performance Best Practices

The xsd:key element is not supported within an Appian CDT. This element is used to define a key constraint for an element or a group of elements. Appian does not support key constraints in CDTs, as they are not relevant for data storage or manipulation. Instead, Appian uses primary keys and foreign keys to enforce uniqueness and referential integrity in CDTs. These keys are specified using the @Id and @JoinColumn JPA annotations, respectively. References: Supported XSD Elements and JPA Annotations

When creating a Web API, you need to configure two items in the Administration Console: an API key and a service account. An API key is a unique identifier that is used to authenticate requests to your Web API. You can create and manage API keys in the Administration Console under Integration > API Keys. A service account is a user account that is used to execute the Web API expression rule. You can select a service account in the Administration Console under Integration > Web APIs when you create or edit a Web API. References: [Web APIs], [API Keys], [Service Accounts]
