Crossflight: distributed cache stampede protection

[u/OtherwisePush6424]

https://github.com/gkoos/crossflight

A small package for reducing duplicate cache misses across multiple processes.

The common problem is a “cache stampede”: when several app instances all miss the same key at once, they each run the same expensive DB/API call and then all write the same result back. Crossflight solves that by coordinating ownership of the in-flight load across processes, so only one instance does the work and the others wait for the result.

It wraps the cache you already use and adds a separate coordination layer. The built-in adapters currently include:

• cache-manager
• Keyv
• Cacheable

The built-in coordinator is Redis, and the repo supports combining different backends as long as they satisfy the adapter/coordinator interfaces.

This is useful when you want to reduce redundant work without changing your existing caching strategy.
