This is Part 5 of the IKVS series, "Implementing a Key-Value Store". You can also check the Table of Contents for other parts. In this article, I will study the actual implementations of hash tables in C++ to understand where are the bottlenecks. Hash functions are CPU-intensive and should be optimized for that. However, most of the |

Introduction Recently, I have been working on a project that dealt with large sets of latency measurements. For these, I always needed to capture percentile values (e.g., p50, p95, p99, etc.). Since I was working with SQLite, I naturally used the stats extension to calculate those percentiles, which worked OK until it didn't! I realized... |

Few data-structures are more ubiquitous in real-world development than the hash table. Nearly every major programming features an implementation in its standard library or built into the runtime. Yet, there is no conclusive best strategy to implement one and the major programming languages diverge widely in their implementations! I did a survey of the Hash map implementations in Go, Python, Ruby, Java, C#, C++, and Scala to compare and contrast how they were implemented. |
