ETS-backed storage for SubscriptionItem resources.
Uses the shared store pattern via use PaperTiger.Store which provides:
- GenServer wraps ETS table
- Reads go directly to ETS (concurrent, fast)
- Writes go through GenServer (serialized, safe)
Architecture
- ETS Table:
:paper_tiger_subscription_items(public, read_concurrency: true) - GenServer: Serializes writes, handles initialization
- Shared Implementation: All CRUD operations via PaperTiger.Store
Examples
# Direct read (no GenServer bottleneck)
{:ok, subscription_item} = PaperTiger.Store.SubscriptionItems.get("si_123")
# Serialized write
subscription_item = %{id: "si_123", subscription: "sub_123", ...}
{:ok, subscription_item} = PaperTiger.Store.SubscriptionItems.insert(subscription_item)
# Query helpers (direct ETS access)
subscription_items = PaperTiger.Store.SubscriptionItems.find_by_subscription("sub_123")Summary
Functions
Returns a specification to start this module under a supervisor.
Clears all subscription_items from the store (all namespaces).

Finds subscription items by subscription ID.
Retrieves a subscription_item by ID.
Inserts a subscription_item into the store.

See Supervisor.
@spec clear() :: :ok
Clears all subscription_items from the store (all namespaces).
Serialized write - goes through GenServer.
Useful for test cleanup. Note: This clears ALL data, not just
the current namespace. For namespace-specific cleanup, use
clear_namespace/1.
@spec clear_namespace(pid() | :global) :: :ok
Clears all subscription_items for a specific namespace.
Used by PaperTiger.Test to clean up after each test.
@spec count() :: non_neg_integer()
Counts total subscription_items in current namespace.
Direct ETS access - does not go through GenServer.
@spec delete(String.t()) :: :ok
Deletes a subscription_item from the store.
Serialized write - goes through GenServer. Data is scoped to the current test namespace.
@spec delete_by_subscription(String.t()) :: :ok
Deletes all subscription items for a given subscription.
Serialized write - goes through GenServer.
Finds subscription items by subscription ID.
Direct ETS access - does not go through GenServer.
Retrieves a subscription_item by ID.
Direct ETS access - does not go through GenServer. Data is scoped to the current test namespace.
Inserts a subscription_item into the store.
Serialized write - goes through GenServer to prevent race conditions. Data is scoped to the current test namespace.
@spec list(keyword() | map()) :: PaperTiger.List.t()
Lists all subscription_items with optional pagination.
Direct ETS access - does not go through GenServer. Data is scoped to the current test namespace.
Options
:limit- Number of items (default: 10, max: 100):starting_after- Cursor for pagination:ending_before- Reverse cursor
Returns all items in a specific namespace.
Useful for debugging test isolation.
@spec prefix() :: String.t() | nil
Returns the ID prefix for this resource.
@spec start_link(keyword()) :: GenServer.on_start()
Starts the subscription_item store GenServer.
@spec table_name() :: atom()
Returns the ETS table name for this store.
Updates a subscription_item in the store.
Serialized write - goes through GenServer. Data is scoped to the current test namespace.
