Schvalne jsem vystrachal kus prispevku z roku 2001 v comp.databases, kde Heikki Tuuri vysvetluje, proc implementoval InnoDB do MySQL a ne do PostrgreSQL: The first reason was that in MySQL there is a standardized interface to lower level storage managers (called table handlers in MySQL) which MyISAM, BDB, and InnoDB use. I have not studied PostgreSQL source at that detail, but the object-relational features there may require something extra from the storage manager. Another reason is speed: InnoDB was designed to be the fastest disk-based database engine in the world. Also MySQL SQL interpreter is fast. The combination MySQL/InnoDB is thus only 30 % slower than a standalone InnoDB and in many tests faster than the standard table type of MySQL. [...] The third reason was that Monty Widenius, the writer of MySQL lives in the same town as I :). > Muj povrchni odhad je , ze vice jak polovina web > aplikaci pouziva MySQL. To je snad take dukaz neceho... A dival ses nekdy, jake verze MySQL napr. ISP provozuji a s jakym enginem? Vetsinou jsou to verze 4.1 s MyISAM... pf
