When should I use HyperLogLog instead of a Set?

Use HyperLogLog when you need to count unique elements (cardinality) across very large datasets where memory efficiency is more important than 100% precision. It uses only 12KB regardless of the number of items.

Can I use this for real-time location tracking?

Yes, the Geospatial patterns include GEOADD and GEOSEARCH commands, which are optimized for updating and querying coordinates in real-time with high throughput.

What is the memory impact of large Bitmaps?

A bitmap can grow up to 512MB. If you set a high bit offset (e.g., bit 100,000,000), Redis allocates all preceding memory. This skill includes strategies for segmenting bitmaps to avoid memory spikes.

How do Redis Streams handle consumer crashes?

Redis Streams use Consumer Groups and Pending Entries Lists (PEL). If a consumer crashes, this skill provides patterns for using XAUTOCLAIM to reassign and process stale messages.

Database Management

Implement specialized Redis data structures including Bitmaps, HyperLogLog, Streams, and Geospatial indexes for complex use cases.

About

This skill provides expert guidance for mastering advanced Redis data structures, enabling developers to build high-performance, memory-efficient applications. It covers sophisticated patterns such as Bitmaps for user activity tracking, HyperLogLog for probabilistic cardinality estimation at scale, Streams for robust event-driven architectures with consumer groups, and Geospatial indexes for location-based services. With built-in troubleshooting for common issues like bitmap memory explosion and stream consumer lag, this skill ensures production-grade implementation of Redis's most powerful specialized features.

Key Features

Efficient Bitmap operations for millions of user flags and activity tracking
Detailed troubleshooting guides for common Redis performance bottlenecks
Advanced Geospatial querying for proximity searches and store locators
Comprehensive Redis Streams patterns for reliable event sourcing and messaging
HyperLogLog implementation for unique visitor estimation with minimal memory footprint
1 GitHub stars

Use Cases

Building real-time analytics dashboards for unique active users using HyperLogLog
Implementing location-aware mobile features like 'users nearby' using Geospatial indexes
Developing scalable message processing systems with Redis Stream consumer groups
