## What it is
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

## Facets
- artifact type: library
- maturity: active
- function: serialization
- domain: developer-tools, microservices, data-science
- platform: python, cross-platform
- tags: pickle, lambda-serialization, cluster-computing, remote-execution
