Migrating the TiKV Rust Client from Futures 0.1 to 0.3
This post introduces Nick's experience in migrating the TiKV Rust client from Futures 0.1 to 0.3.
Why Benchmarking Distributed Databases Is So Hard
Benchmarks are hard to get right, and many articles touting benchmarks are actually benchmarketing, showcasing skewed outcomes to sell products. This post introduces some of the motivations for benchmarking and the common tools, and discusses a few things to keep in mind when benchmarking.
The KOST Stack: An Open-Source Cloud-Native Hybrid Database Stack
A new infrastructure pattern is emerging called the KOST stack (Kubernetes, Operator, Spark, TiDB). This blog post introduces each component of the KOST stack and cloud-native HTAP in the wild.
TiDB Passes Jepsen Test for Snapshot Isolation and Single-Key Linearizability
TiDB's first official Jepsen Test report is published. This post introduces some additional context to the test results and PingCAP's thoughts on what's next.
Try to Fix Two Linux Kernel Bugs While Testing TiDB Operator in K8s
This post introduces how the EE team at PingCAP tackled two Linux kernel bugs while testing TiDB Operator in K8s. PingCAP engineers also hope the K8s community, RHEL and CentOS can help fix these bugs thoroughly in the near future.
Implement Raft in Rust
As an open-source distributed scalable HTAP database, TiDB uses the Raft Consensus Algorithm in its distributed transactional key-value storage engine, TiKV, to ensure data consistency, auto-failover, and fault tolerance. TiDB has thus far been used by more than 200 companies in their production environments in a wide range of industries, from e-commerce and food delivery, to fintech, media, gaming, and travel.
A TiKV Source Code Walkthrough – Raft Optimization
Paxos or Raft is frequently used to ensure data consistency in the distributed computing area. But Paxos is known for its complexity and is rather difficult to understand while Raft is very simple. Therefore, a lot of emerging databases tend to use Raft as the consensus algorithm at its bottom layer. TiKV is no exception.
Why did we choose Rust over Golang or C/C++ to develop TiKV?
Every developer has his/her favorite programming language. For the TiKV team members, it's Rust.
The Design and Implementation of Multi-raft
The goal of TiKV is to support 100 TB+ of data and it is impossible for one Raft group to make it, we need to use multiple Raft groups, which is called Multi-raft.
A TiKV Source Code Walkthrough – Raft in TiKV
TiKV uses the Raft algorithm to implement the strong consistency of data in a distributed environment. This blog introduces the details how Raft is implemented.
