Requirements
Functional Requirements:
- Create and Share Pastes: Users should be able to create a new paste by entering text content. Once created, the paste is stored and can be shared through a unique URL.
- Plain Text Storage: The service generally supports plain text as the primary format, which suits its purpose of sharing code snippets, notes, or other text-based content.
- Optional Expiration: Users might want to specify how long the paste should be valid. After the expiration period, the paste should no longer be accessible.
- Unique URL/ID Generation: Each paste must be accessible via a unique identifier in the URL. This ensures that users can easily share and retrieve their pastes.
- Read Access: Users should be able to retrieve the content of a paste using its unique URL.
- No User Accounts Needed: For simplicity, many pastebin services allow users to create and manage pastes without needing to register an account, making it easy and fast to use.
- Search functionality (optional): Although not part of the basic requirement, users may benefit from the ability to search through the pastes if implemented later on.
Non-Functional Requirements:

API Design
Define the APIs expected from the system. This is your chance to analyze and define the read and write paths so that you can come up with the high-level design...
High-Level Design
Describe the overall system architecture. Identify the main components needed to solve the problem end-to-end. Use the diagramming tool to create a block diagram.
Detailed Component Design
Deep dive into 2-3 key components. Explain how they work, how they scale, discuss tradeoffs, capacity, and any relevant algorithms or data structures.
