# Waltz: A Distributed Write-Ahead Log - Host: [wecode.wepay.com](https://links.thingelstad.xyz/hosts/wecode.wepay.com/) - Saved: September 12, 2019 (2019-09-13T01:24:46Z) - Record: https://links.thingelstad.xyz/links/a17f8dbcb8ed/ - JSON: https://links.thingelstad.xyz/links/a17f8dbcb8ed.json ## What Jamie wrote Streaming systems are very popular right now, but many of them have challenges around once-only delivery and transactional ordering. Waltz seems to solve that. > Waltz is similar to existing log systems like Kafka in that it accepts/persists/propagates transaction data produced/consumed by many services. However, unlike other systems, Waltz provides a machinery that facilitates a serializable consistency in distributed applications. It detects conflicting transactions before they are committed to the log. Waltz is regarded as the single source of truth rather than the database, and it enables a highly reliable log-centric system architecture. Definitely a highly focused service, but for certain solutions this would be a big deal. ## Facts - Kind: [Page](https://links.thingelstad.xyz/kinds/page/) ## Appears in - [WT117: Weekly Thing #117 / Sep 14, 2019](https://weekly.thingelstad.com/archive/117/), Notable Links 📌 ## Saved the same week - [Official Google Webmaster Central Blog: Evolving “nofollow” – new ways to identify the nature of links](https://links.thingelstad.xyz/links/f96d0f4cf341/) (webmasters.googleblog.com, September 12, 2019) - [Apple Watch Series 5: The MacStories Overview - MacStories](https://links.thingelstad.xyz/links/b7019194a3ff/) (macstories.net, September 12, 2019) - [The iPhone and Apple’s Services Strategy – Stratechery by Ben Thompson](https://links.thingelstad.xyz/links/0bd549f71e02/) (stratechery.com, September 12, 2019) - [When Waterfall Principles Sneak Back Into Agile Workflows](https://links.thingelstad.xyz/links/7acd58f5ffcd/) (hbr.org, September 12, 2019) - [The importance of humility in product management - Thor Mitchell - Medium](https://links.thingelstad.xyz/links/3918917ac738/) (medium.com, September 12, 2019) ## Elsewhere - Wayback Machine: https://web.archive.org/web/*/https://wecode.wepay.com/posts/waltz-a-distributed-write-ahead-log
