@ancient-wolf-19325 What does FastSerialization do?

FastSerialization in Flyte enables "fast registration" by packaging user code and dependencies into a compressed archive (e.g., .tar.gz), which is uploaded to a remote location. At execution time, this archive is downloaded and unpacked in the task container, allowing rapid iteration without rebuilding the container image for every code change. This significantly speeds up the workflow registration process when system-level dependencies remain unchanged, as only the code archive is updated and transferred, not the entire image. According to the documentation, this is controlled by the

FastSerializationSettings

object, which specifies if fast serialization is enabled, the destination directory, and the distribution location for the archive (flytekit.configuration.FastSerializationSettings). This approach is ideal for development and CI/CD scenarios, as it decouples code changes from image builds, reducing registration time from minutes to seconds. The process involves serializing entities, packaging the code, uploading the archive, and updating the registration to reference the new code location (flytekit.tools.repo.register).
