Understanding Murmur Hashing: When and Why to Use

Hashing is a cornerstone of computer science, used extensively in data structures, cryptography, and distributed systems. Among various hashing algorithms, MurmurHash stands out for its speed, efficiency, and suitability for non-cryptographic applications. In this blog, we will delve into what MurmurHash is, when to use it, and how it compares to other hashing techniques, along with practical examples.

Understanding PostgreSQL EXPLAIN: A Guide to Query Optimization

PostgreSQL's EXPLAIN command is a powerful tool that provides insights into how a query will be executed. It helps developers and database administrators identify potential performance issues in their queries. In this blog, we will explore what EXPLAIN is, when to use it, how to interpret its output, and techniques for optimizing queries based on the insights it provides.

Grok Parser in Go: A Detailed Guide for Log Parsing

Logs play a vital role in understanding how applications and systems perform, but unstructured log data can be hard to analyse. The Grok parser helps by converting raw logs into structured, readable formats. It is widely used for extracting information such as timestamps, error codes, and IP addresses from logs, making them easier to analyse and query.

Simplifying Docker Compose Configurations with Aliases

When building applications with Docker Compose, it's common to encounter duplicate configurations across services, especially as projects grow and configurations become more complex. The benefits of using aliases in Docker Compose are crucial in this scenario. Docker Compose aliases provide a way to streamline this setup, reduce redundancy, and simplify logging configuration.

WHERE vs PREWHERE in ClickHouse

ClickHouse is a high-performance, columnar database designed for analytics and big data applications. One of ClickHouse's standout features is its ability to perform filtering directly on compressed data, enabling faster results compared to traditional relational databases. While working with ClickHouse, you will often encounter the WHERE and PREWHERE clauses, both of which are used to filter data. But what is the difference between WHERE and PREWHERE, and when should you use one over the other?

Understanding setImmediate() vs process.nextTick() in Node.js

Node.js is a powerful runtime environment that allows you to handle asynchronous I/O operations efficiently using its event-driven architecture. Asynchronous operations in Node.js rely heavily on the event loop, and understanding how certain functions like process.nextTick() and setImmediate() interact with the event loop is essential for building fast, responsive applications.
