Self-Hosted Compressed Bitmap Indexes: Roaring Bitmap vs EWAH vs BitMagic vs bitset

Fri, 19 Jun 2026 00:00:00 +0000

Introduction

Bitmap indexes are one of the oldest and most powerful indexing techniques in database systems — they encode set membership as bit strings where each bit position represents a row or document ID. When you need to compute fast intersections, unions, or differences of large datasets (AND, OR, NOT over millions of records), bitmaps are unmatched.

Self-Hosted Consistent Hashing: Jump Hash vs Ring Hash vs Rendezvous Hashing Libraries

Introduction

When building self-hosted distributed systems — from caching layers to load balancers to sharded databases — one fundamental problem keeps appearing: how do you distribute data or requests across a changing set of servers without reshuffling everything?

Self-Hosted Probabilistic Data Structures: Bloom Filters vs Cuckoo Filters vs HyperLogLog vs Count-Min Sketch

Introduction

When building self-hosted monitoring systems, analytics pipelines, or distributed databases, you frequently need to answer questions like “have I seen this user before?”, “how many unique visitors today?”, or “what are the top 100 most frequent items?” — but at massive scale where exact answers are too expensive.

Self-Hosted Raft Consensus Libraries: HashiCorp Raft vs Dragonboat vs braft vs raft-rs

What Are Raft Consensus Libraries?

When building distributed systems, one of the hardest problems is getting multiple nodes to agree on state. The Raft consensus algorithm, designed by Diego Ongaro and John Ousterhout in 2014, has become the de facto standard for implementing replicated state machines due to its understandability compared to Paxos.
