When it fits — and when it doesn’t

Known weaknesses

Each one links to the public issue, changelog or docs page it came from, where we have one.

1. 01

   Limited scalability for large datasets

   Uses JSON files for storage, which can become inefficient and slow with larger data volumes

2. 02

   Poor performance in high concurrency scenarios

   File-based storage mechanism can lead to contention issues when multiple processes access the database simultaneously

3. 03

   Lack of advanced querying capabilities

   Only supports basic key-value operations, lacking support for complex queries or indexing

4. 04

   No built-in data consistency guarantees

   Simple file-based storage does not provide transactional support or ACID compliance

What it does well

• Simple and lightweight key-value storage

• Easy to use with a Pythonic API

• Persistent storage using JSON files
