Aggregate query statistics hide the forest of cheap queries.

Idle transactions hold locks and block vacuums, turning one forgotten connection into a cascading outage.

本文讨论了FoundationDB中的TLog（事务日志）机制，强调其在客户端提交中的重要性。TLog通过将变更日志复制到多个LogServer来确保数据持久性，提交成功的条件是所有指定副本的日志都持久化。文章还探讨了Durable Version（DV）和Known Committed Version（KCV）的概念，以及在恢复过程中确保已承诺事务可找回的方法。TLog的设计使存储与提交路径解耦，提高了I/O效率，但可能导致短暂的读延迟。

PostgreSQL's isolation levels hold surprises: read uncommitted silently becomes read committed, repeatable read forbids phantom reads the standard permits, and…

PostgreSQL's `DEFERRABLE` transaction mode only works with `SERIALIZABLE READ ONLY` transactions, where it waits for a safe snapshot to eliminate…

Blockchain data indicate large transaction volumes for stablecoins, often cited in trillions of dollars, but most of this activity isn’t tied to real-world payments. Here’s what the data really show.

At first glance, the idea that an idle session could lead to a transaction wraparound might seem counterintuitive. Most PostgreSQL users are familiar with how long-running queries or open...

Global transaction banking could face headwinds from customer demands, lower rates, heightened competition, and geopolitical uncertainty, but distinctive players could boost profitability.

Learn about how Global Transaction Identifiers (GTID's) and how they are used with MySQL replication.

I have microservice architecture. I implement a distributed transaction flow (2-phase commit), kafka, and 1 coordinator service. So, my problem is in each step of preparation I am calling an...

This blog explains how you can set up inbound replication without using global transaction identifiers on the source.

Spring框架中的org.springframework.transaction包提供了强大的事务处理工具和抽象，简化了开发人员管理数据库交互的过程。通过有效利用Spring的事务管理功能，可以确保数据的完整性、一致性和可靠性，满足现代企业环境需求。

本文通过三个C#示例方法分析了在EF Core中处理事务的不同方式，推荐使用方法三来处理事务，正确提交或回滚事务，并及时释放资源。

SwiftUI 因其简便的动画 API 与极低的动画设计门槛而广受欢迎。但是，随着应用程序的复杂性增加，开发者会逐渐发现，尽管动画设计变得前所未有的简单，但要实现精确细致的动画控制并非易事。同时，在 SwiftUI 的动画系统中，Transaction 始终有点像谜一样的存在。无论是官方资料还是第三方文章，都很少对其运作机制进行系统的阐述。本文将通过探讨 Transaction...
