SharDB

説明

This is intended for larger WordPress Network installs using an existing 1-3 character MD5 hash (by blog id) based multi-DB sharding structure. It supports 16, 256 or 4096 database shards. It also supports a separate database for blog id 1 and multiple VIP databases (home & VIP code contribution by Luke Poland).

It should support any plugin that works with (and accesses all data via) the regular WordPress database code.

It has been used to power MU version 2.7.1 through WordPress 4.8 sites and upgrade sites from 2.7.1 through to the WordPress 4.8.

A detailed installation guide can be purchased for a nominal fee.

This plugin is based on HyperDB which is the database plugin used by WordPress.com. Like HyperDB, this plugin autodetects whether a query is requesting a global or blog table.

This plugin was so great, I was using multi-db developed by wpmudev before, but it wasn't working after php7. So I moved multi-db to shardb. I want to say big thanks to the developer and let wordpress users to know that this plugin is still working following environment. WordPress: 5.1.1 PHP: 7.1.X MySQL: 8.X

This plugin is not compatible with current version of WordPress. Error: SharDB must set a database connection for use with escaping.
