mysql ha造句

MySQL has really crappy table locking, and blocks everything when certain slow operations are being done.
In summary, Postgres fully supports schemas but lacks some functionality MySQL has with databases, while MySQL does not even attempt to support true schemas.
As of Umbraco 6, support for MySQL has waned, as the development team has spent more time supporting Microsoft's SQL Server products.
It can therefore be said that MySQL has implemented cross-database functionality, skipped schema functionality entirely, and provided similar functionality into their implementation of a database.
In this context, MySQL databases are analogous in function to Postgres-schemas, insomuch as Postgres lacks off-the-shelf cross-database functionality that MySQL has.

A version where MySQL has been replaced by PostgreSQL is called LAPP, or sometimes by keeping the original acronym, LAMP ( Linux / Apache / Middleware ( Perl, PHP, Python, Ruby ) / PostgreSQL ).
MySQL has received positive reviews, and reviewers noticed it " performs extremely well in the average case " and that the " developer interfaces are there, and the documentation ( not to mention feedback in the real world via Web sites and the like ) is very, very good ".
I have spent the better part of the week reading about scaling MySQL, PHP, and so forth, but I really find it difficult to find information on how to do it-most specifically with MySQL . While MySQL has a lot of documentation on their site about scaling, what I am interested in are some PHP-based approaches to scaling ( preferably Master + Slaves ) with MySQL . I browsed around the MediaWiki code, but it's loadbalancing class is very large and complex.
