NAME

6       Apache::DBI::Cache::mysql - a Apache::DBI::Cache plugin
7

SYNOPSIS

9         use Apache::DBI::Cache plugin=>'Apache::DBI::Cache::mysql',
10                                ...;
11        or
12
13         use Apache::DBI::Cache;
14         use Apache::DBI::Cache::mysql;
15

DESCRIPTION

17       NOTE: Read Apache::DBI::Cache before.
18
19       "DBD::mysql" allows many different DSN syntaxes for connecting to the
20       same database server and the same database. This plugin transforms them
21       to a standard format thus allowing better DBI handle caching. Further,
22       if "port" is omitted the standard port 3306 is inserted. The actual
23       database is deleted from the DSN and replaced by a "USE database"
24       command.
25
26       So, DBI connects to the following DSNs as the same user at different
27       times are actually performed with the same DSN "host=server;port=3306".
28       Subsequently "USE db[1-3]" commands are issued before passing the
29       handle to the caller.
30
31         dbi:mysql:dbname=db1;host=server
32         dbi:mysql:db2:server:3306
33         dbi:mysql:port=3306;database=db3;host=server
34
35       Apache::DBI::Cache can cache them all under the same key. So only one
36       real database connection is needed instead of 3 without the plugin.
37
38       Furthermore, "mysql_auto_reconnect" is turned off.
