Hi, Some of you might already know GOODS, programmed almost entirely by Konstantin Knizhnik - if not you should really have a look at it right now (be warned: consuming this extraordinary work might change your levels about the required quality of a 'good programmer' forever. At least this happend to me... ;): http://www.garret.ru/~knizhnik/goods.html
Some core features of this backend (as they come to my mind): -> full ACID transaction support -> distributed stoarge management (->distributed transactions) -> multible reader/single writer (is this called MVCC within PostgreSQL?) -> dual client side object cache -> online backup (snapshot backup AND permanent backup) -> nested transactions on object level -> transaction isolation levels on object level -> object level shared and exclusive locks -> excellent C++ programming interface -> WAL -> garbage collection for no longer reference database objects -> fully thread safe client interface -> JAVA client API -> very high performance as a result of a lot of fine tuning -> asyncrous event notification on object instance modification -> extremly high code quality -> a one person effort, hence a very clean design -> the most relevant platforms are supported out of the box -> complete build is done in less than a minute on my machine -> it's documented ... The licensing of this coding wonder: >>> PUBLIC DOMAIN <<< I'm using GOODS quiet a while now in the context of my development activities for a native XML database and have very promissing experiences concerning performance and stability of GOODS. E.g.: The performance seems to be better than sleepycat's berkeley db library - especially with mutliple simultanous transactions... Maybe the only restriction to use this backend in postgres from now on: it's completely C++ ... I'm wondering why there is no SQL frontend yet for this execellent backend... You may want to look also at a comparision chart of some other backends than GOODS (some of them from the same author!!! I'm wondering how he was able to code all this...): http://www.garret.ru/~knizhnik/compare.html kind regards, Robert ---------------------------(end of broadcast)--------------------------- TIP 4: Don't 'kill -9' the postmaster
