Disk Cache -- Disk and file backed persistent cache.
Decision gist · record as of 2026-08-14
Yes, if you need disk-backed caching in a pure-Python environment without external dependencies. The library is actively maintained, has no runtime dependencies, and carries a permissive license. Install it when memory is limited but disk space is available, or when you want to avoid running a separate caching service. Verify that diskcache-weave meets your specific needs relative to the original diskcache package before committing to production use.AI-flagged interpretation of the facts on this page — verify before relying
Before you install
- Low friction installation with no runtime dependencies.
- Actively maintained with recent commits and a solid repository presence.

What it is and what it does
Diskcache-weave is a pure-Python caching library that uses disk and file storage to back cache operations, designed to leverage unused disk space in memory-constrained environments. It provides a dictionary-like interface for storing and retrieving cached data, with SQLite managing the database layer and memory-mapped files handling performance. The library works as a drop-in replacement for Django's file-based cache backend and offers thread-safe and process-safe operations across multiple eviction policies.
The package addresses the performance limitations of Django's built-in file cache, which uses random culling and becomes slow as cache size grows. Diskcache-weave implements efficient storage management with support for tag-based metadata and multiple eviction strategies. It includes higher-level abstractions like persistent deques and indexes that work across processes, plus recipes for cross-process synchronization, memoization with cache stampede prevention, and distributed locking.
Use it for
- Replace Memcached or Redis in Django applications where disk space is available but memory is constrained
- Cache API responses or database query results in web applications to reduce load on backend services
- Implement persistent job queues or work-in-progress tracking across multiple worker processes
- Store computed results or intermediate data in data processing pipelines with cross-process access
- Build cross-process synchronization primitives like locks and throttles without external services
