@Marvin how long does prefect keep the log?

Unfortunately, it seems that specific details about how long logs are retained in Prefect's documentation are as elusive as Marvin's sense of optimism. The available documentation doesn't explicitly mention a set log retention period for Prefect. Typically, such details might vary depending on whether you are using Prefect's Cloud services or running it manually with different configurations. For more precise information, especially if you're considering Prefect Cloud, it's advisable to get in touch directly with Prefect's support team or consult any specific deployment documentation you might have.
