Module-based cache instances for FerricStore.

Each module that calls use FerricStore gets a local direct cache instance with its own shards, ETS tables, data directory, and config. The default application instance owns the Raft system.

Usage

defmodule MyApp.Cache do
  use FerricStore,
    data_dir: "/data/cache",
    shard_count: 4,
    max_memory: "1GB"
end

# In your supervision tree:
children = [MyApp.Cache]

# Then use it:
MyApp.Cache.set("key", "value")
{:ok, "value"} = MyApp.Cache.get("key")

Multiple instances

defmodule MyApp.Sessions do
  use FerricStore,
    data_dir: "/data/sessions",
    shard_count: 2
end

MyApp.Cache.set("page:home", html)
MyApp.Sessions.set("sess:abc", session_data)

Options

  • :data_dir — base directory for Bitcask data files (required)
  • :shard_count — number of shards (default: 4)
  • :max_memory_bytes — maximum memory budget (default: 1GB)
  • :keydir_max_ram — maximum ETS keydir memory (default: 256MB)

  • :eviction_policy — :volatile_lfu | :allkeys_lfu | :noeviction (default: :volatile_lfu)

  • :hot_cache_max_value_size — max value size for ETS caching (default: 65536)
  • :read_sample_rate — LFU sampling rate (default: 100)

Functions

append(key, suffix)

See FerricStore.API.Strings.append/2.

await_ready(opts \\ [])

@spec await_ready(keyword()) :: :ok

Blocks until FerricStore is fully ready to serve requests.

Polls Health.check/0 until all shards are alive and all Raft leaders are elected. Returns :ok when ready, raises on timeout.

Call this in your application's start/2 after FerricStore is in your supervision tree, or in test setup, to ensure writes won't fail.

Options

  • :timeout - max milliseconds to wait (default: 30_000)
  • :interval - polling interval in ms (default: 100)

Examples

# In your Application.start/2:
def start(_type, _args) do
  children = [
    {FerricStore, []},
    MyApp.Repo,
    MyAppWeb.Endpoint
  ]
  opts = [strategy: :one_for_one, name: MyApp.Supervisor]
