LemonCore.Store.JsonlBackend (lemon_core v0.1.0)

View Source

Persistent JSONL-based storage backend with dynamic table support.

Stores all operations as append-only JSONL (JSON Lines) files. Each logical table is stored in a separate file within the configured directory.

Options

  • :path - Required. Directory path where JSONL files will be stored.

File Format

Each line is a JSON object with the structure:

{"op": "put"|"delete", "key": <key>, "value": <value>, "ts": <unix_ms>}

On init, all existing *.jsonl files in the store directory are loaded. New tables are created on first write.
