Persistent disk storage backend using DETS.

Provides durable storage that survives node restarts. Data is written to disk and automatically persisted.

Features

• Survives node restarts
• Auto-save at configurable intervals
• Same API as ETS backend

Limitations

• 2GB maximum file size
• Slower than ETS (disk I/O)
• No concurrent writes from multiple processes

Usage

{:ok, ref} = Grove.Storage.DETS.init(file: "/var/lib/grove/crdts.dets")

# Save a CRDT
:ok = Grove.Storage.DETS.save(ref, {:counter, "views"}, crdt_state)

# Load a CRDT
{:ok, crdt_state} = Grove.Storage.DETS.load(ref, {:counter, "views"})

# Close when done
:ok = Grove.Storage.DETS.close(ref)

Options

• :file - Required. Path to the DETS file
• :table - Table name (default: :grove_dets_storage)
• :auto_save - Auto-save interval in ms (default: 60000)
