Execute Concurrently

Execute functions concurrently

The following Dagger Function demonstrates how to use native-language concurrency features (errgroups in Go, task groups in Python), and promises in TypeScript to execute other Dagger Functions concurrently. If any of the concurrently-running functions fails, the remaining ones will be immediately cancelled.

Example

Execute a Dagger Function which performs different types of tests by executing other Dagger Functions concurrently.
