Supabase.Storage.Cache (supabase v0.2.0)
Provides caching mechanisms for Supabase Storage Buckets.
This module acts as a GenServer that offers caching capabilities, especially for bucket-related operations in Supabase Storage. The caching is backed by the :ets (Erlang Term Storage) to provide in-memory storage and fast retrieval of cached data.
Features
- Bucket Caching: Store and retrieve buckets by their unique identifier.
- Cache Flushing: Clear the cache when necessary.
- Configurable Cache Size: Limit the number of items that can be stored in the cache.
Usage
Starting the Cache Server
Supabase.Storage.Cache.start_link(%{cache_max_size: 200})Caching Buckets
buckets = [%{id: "bucket_1", ...}, %{id: "bucket_2", ...}]
Supabase.Storage.Cache.cache_buckets(buckets)Retrieving a Cached Bucket by ID
Supabase.Storage.Cache.find_bucket_by_id("bucket_1")Clearing the Cache
Supabase.Storage.Cache.flush()Implementation Details
The cache uses the :ets module for in-memory storage of buckets. The number of buckets cached is controlled by the :cache_max_size option (default: 100). When the cache is close to exceeding its maximum size, older entries are removed to accommodate new ones.
