Behaviour for building cache keys in Lotus.

Implement this behaviour to customize how cache keys are generated for discovery (schema introspection) and result (query execution) caching.

The default implementation (Lotus.Cache.KeyBuilder.Default) preserves the existing key generation logic.

Configuration

config :lotus,
  cache: %{
    adapter: Lotus.Cache.ETS,
    key_builder: MyApp.CustomKeyBuilder
  }

Example

defmodule MyApp.CustomKeyBuilder do
  @behaviour Lotus.Cache.KeyBuilder

  @impl true
  def discovery_key(params, scope) do
    # Custom key logic for discovery cache entries
    Lotus.Cache.KeyBuilder.Default.discovery_key(params, scope)
  end

  @impl true
  def result_key(body, bound, opts, scope) do
    # Custom key logic for result cache entries
    Lotus.Cache.KeyBuilder.Default.result_key(body, bound, opts, scope)
  end
end
