gitconnected·2ySystem Design Interview Question: Design URL Shortener
Designing a URL shortener tool requires considering functional and non-functional requirements, estimating the number of unique URLs needed, and implementing key components like users, load balancer, web servers, URL shortener service, and database. The API design includes creating a short URL and redirecting to the long URL. The database should be optimized for fast read and write operations, and the URL shortener service can use methods like hashing, auto-increment IDs, or custom algorithms. Caching and database scaling strategies are important for high availability and low latency. Security considerations include input validation, rate limiting, monitoring and logging, obfuscation, and link expiration.

Towards Dev·2yWhat Is a Streaming Database?
A streaming database is designed to process large amounts of real-time streaming data, providing real-time insights and analysis. It is ideal for latency-critical applications such as real-time analytics, fraud detection, network monitoring, and the Internet of Things (IoT). Streaming databases differ from traditional databases in their processing approach and can be used alongside other data systems for streaming ingestion and streaming analytics. They also differ from OLTP and OLAP databases in terms of ACID compliance, data correctness, and query optimization.

This Dot·2yIntro to EdgeDB
EdgeDB is a graph-relational database that provides a novel approach to handling common pain points in data modeling. It offers a powerful schema system, support for defining relations/associations, computed properties, and access policies. EdgeQL is the query language used to interact with the database. EdgeDB nudges users to move more application logic into the database layer, providing constraints, global variables, contexts, and authorization support out-of-the-box. EdgeDB offers both a basic client for executing queries and a TypeScript query builder for type-safe queries. The CLI and Admin UI provide additional tools for managing EdgeDB projects and databases.
