Serverless Key-Value Store (Dict)

1 post · May 2025

What this trail covers

Modal's Dict primitive provides a serverless TTL'ed key-value store accessible from any container within a workspace. Recent enhancements include unlimited storage, a revised expiry policy (7 days since last read or write), data durability, and a locking primitive via the `.put()` method's `skip_if_exists` flag. These improvements enable advanced use cases like LRU-like caching with extended TTLs for hot entries and distributed locking for 'exactly once' semantics.

  1. Modal's serverless KV store gets its limit raised to infinityIntroduced unlimited storage for Dicts, changed item expiry policy to 7 days since last read OR write, added data durability, and implemented a locking primitive via the `.put()` method's `skip_if_exists` flag. This enables LRU-like caching and distributed locking for 'exactly once' semantics.
