prefect 3.0.3

Cache Rules Everything Around Me

on Python PyPI

This release introduces improvements to cache policy configuration, offering developers more control and flexibility in managing task result caching:

• Customizable Storage Location: Specify where cache entries are stored using the key_storage parameter.
• Configurable Isolation Level: Set the isolation level for cache access with the isolation_level parameter.
• Locking Mechanism: Implement concurrent access control using the lock_manager parameter.

These enhancements allow for more sophisticated caching strategies, improving performance and resource management in complex workflows.

To learn more about these changes, check out the task caching docs.
