them. So there they sit, taking up space and doing no good to anyone. Even with a garbage collect thread, some active transaction has to stumble over deleted records or records with unneeded back versions immediately (or at least when the transaction gets some cycles). The dedicated garbage collection thread should clean up all the records on a page, but not until an active transaction tells it that there’s transaction is dead and the reader will either clean up the mess or notify the garbage collect thread to do so.

положения о генераторах 2.1. Что такое генератор? Думайте о генераторе, как о “потокобезопасном” (“thread-safe”) целочисленном счетчике, который расположен внутри базы данных Firebird. Вы можете создать GEN_ID(gen_spTestProgress, 0) асинхронно с реальной обработкой записей (например, в другом потоке [thread]), чтобы посмотреть, сколько записей было обработано, и отображать полученное значение в некотором0 码力 | 23 页 | 227.10 KB | 1 年前3Firebird Generator Guide: A guide on how and when to use generators in Firebird
Introduction 2 Chapter 2. Generator Basics 2.1. What is a generator? Think of a generator as a “thread-safe” integer counter that lives inside a Firebird database. You can create one by giving it a name: do a GEN_ID(gen_spTestProgress,0) asynchronously to the actual row fetching (e.g. in a different thread), to see how many rows were processed, and display the value in some sort of progress window.

Generatoren: Grundlagen 2.1. Was ist ein Generator? Man stelle sich einen Generator vor wie einen "Thread-sicheren" Integer-Zähler, der in einer Firebird Datenbank existiert. Man kann einen Generator erzeugen ein GEN_ID(gen_spTestProgress,0) asynchron zur Ausführung der SP aufrufen (z.B. in einem zweiten Thread), um zu sehen, wie viele Sätze bereits abgearbeitet sind, und diesen Wert in einem Fortschrittsbalken0 码力 | 22 页 | 183.60 KB | 1 年前3Firebird 1.0 QuickStart
