It works as a daemon inside the +mysqld process, accept tcp connections, and execute requests from clients. +HandlerSocket does not support SQL queries. Instead, it supports simple CRUD +operations on tables. + +Because of the following reasons, HandlerSocket is much faster than the +mysqld/libmysql pair in some circumstances: + + - HandlerSocket manipulates data without parsing SQL, which causes less + CPU usage. + - HandlerSocket reads many requests from clients and executes their + requests in bulk, which causes less CPU and disk usage. + - HandlerSocket client/server protocol is more compact than the + mysql/libmysql pair, which causes less network usage. + +The current version of HandlerSocket only works with GNU/Linux. The source +archive of HandlerSocket includes a C++ and a Perl client libraries. +Here is a list of other language bindings: + + - PHP + http://openpear.org/package/Net_HandlerSocket + http://github.com/tz-lom/HSPHP + http://code.google.com/p/php-handlersocket/ + - Java + http://code.google.com/p/handlersocketforjava/ + - Python + https://code.launchpad.net/~songofacandy/+junk/pyhandlersocket + - Ruby + https://github.com/winebarrel/ruby-handlersocket + https://github.com/miyucy/handlersocket + - JavaScript(Node.js) + https://github.com/koichik/node-handlersocket + +The home of HandlerSocket is here: + https://github.com/DeNADev/HandlerSocket-Plugin-for-MySQL + +More documents are available in docs-en/ and docs-ja/ directories. + |
