Key Value Data Store

A File-based Key-Value datastore.

It supports Create, Delete and Retrieve functions.

Functionalities

1. It can be initialized using an optional file path. If one is not provided, it will reliably create itself using uuid.
2. Key string capped at 32 characters and Value must be a JSON object capped at 16KB. (These values can be changed in config.py)
3. Every key supports setting a Time-To-Live property when it is created. This property is optional. If provided, it will be evaluated as an integer defining the number of seconds. Once the Time-To-Live for a key has expired, the key will no longer be available for Read or Delete operations.
4. Only one process can access the datastore (local file) at a time.
5. Thread safe.

REST API Endpoints

1. POST /db - Creates an entry in the file database. Payload should contain a 'key' (String), 'value' (JSON payload), 'ttl' (Time to live in milliseconds)
2. GET /db/search/{key} - Retreives the value corresponding to the 'key'
3. DELETE /db/{key} - Deletes the entry corresponding to the 'key'
