AppEngine Functions (Serverless Functions) (DPS)
Please note that invocation of AppEngine functions can trigger the ingest (and therefore implicitly the retention) of additional data or the execution of a DQL query. This might generate additional consumption of Ingest & Process, Retain, and Query dimensions, depending on the use cases.

AppEngine functions are deployed in an environment with 256 MiB RAM and can have a maximum execution time of up to 840 seconds. This differs from the following variants of AppEngine (Serverless) functions:
-
App functions
These functions represent the backend of an app and are built, bundled and deployed together with your custom app. -
Ad hoc functions
Custom code to accomplish specific use cases is referred to as ad hoc functions (or "glue" code). These functions can be invoked from within Notebooks, Dashboards, Workflows, or directly via API. -
Custom actions
App functions that, together with a UI component, can be declared as a custom Workflows action to extend the Workflows app. Custom actions can then be selected as a task within the Workflows app and be executed within the Workflows.
Billable consumption of AppEngine functions occurs when:
- Invoking App functions in a custom app
- Invoking Ad-hoc functions from within Notebooks, Dashboards, Workflows or directly via API
- Invoking Custom actions
The unit of measure for consumption of AppEngine functions is an invocation. One invocation is consumed for each minute (including partial minutes) of function execution time. The total consumption is calculated by multiplying the number of invocations by your rate card price per invocation.
Example
- You add a code section in your Notebook and add custom code, which we refer to as an "Ad-hoc function." The execution of the function takes 45 seconds. This consumes 1 function invocation.
- In your custom app you include an app function to retrieve data from your data source. The execution time of this function is 132 seconds. This consumes 3 invocations (as 3 minutes were started during function execution).
