cloudpickle is a Python library that extends the standard pickle module to serialize constructs like lambda functions and interactively defined classes by value. It is primarily used to ship Python code across a network in cluster and distributed computing setups.

Use cases

• serialize lambda functions in python
• pickle functions defined in jupyter notebook
• send python code to remote workers
• serialize closures for distributed computing
• pickle interactively defined classes

When to choose

• you need to serialize lambdas, closures, or __main__-defined functions/classes
• you ship Python callables to remote hosts or cluster workers
• you use distributed frameworks like dask or ray that need by-value serialization

When to avoid

• you need long-term object storage
• objects must be exchanged across different Python versions
• you only pickle importable module-level objects - stdlib pickle suffices
• untrusted sources may supply the pickle data
