Explanation

Data Storage

All data is stored in the LMDB database. A KEY must be provided for set/get/del operations.

Data Export

Use the export command to save database data to export.json.

Data Import

import <ID> <FILE_PATH>

• <ID>: The unique identifier field for the imported data.
• <FILE_PATH>: The path to the JSON data file.

If the JSON data is formatted as follows:

[
  { "id": 1, "name": "Alice" },
  { "id": 2, "name": "Bob" }
]

Executing import id data.json will store the data using id as the key.
