ETS (Erlang Term Storage) adapter for high-performance in-memory caching.

This adapter provides a fast, process-independent cache using Erlang's built-in ETS tables. It's ideal for applications requiring low-latency access to cached data within a single node.

Features

• In-memory storage with configurable concurrency options
• Direct access to ETS-specific operations
• Very high performance for read and write operations
• Support for atomic counter operations

Options

• :write_concurrency (boolean/0) - Enable write concurrency

• :read_concurrency (boolean/0) - Enable read concurrency

• :decentralized_counters (boolean/0) - Use decentralized counters

• :type - Data type of ETS cache The default value is :set.

• :compressed (boolean/0) - Enable ets compression

Example

defmodule MyApp.Cache do
  use Cache,
    adapter: Cache.ETS,
    name: :my_app_cache,
    opts: [
      read_concurrency: true,
      write_concurrency: true
    ]
end
