WC_Install::get_schema()private staticWC 1.0

Get Table schema.

See https://github.com/woocommerce/woocommerce/wiki/Database-Description/

A note on indexes; Indexes have a maximum size of 767 bytes. Historically, we haven't need to be concerned about that. As of WordPress 4.2, however, we moved to utf8mb4, which uses 4 bytes per character. This means that an index which used to have room for floor(767/3) = 255 characters, now only has room for floor(767/4) = 191 characters.

Changing indexes may cause duplicate index notices in logs due to https://core.trac.wordpress.org/ticket/34870 but dropping indexes first causes too much load on some servers/larger DB.

When adding or removing a table, make sure to update the list of tables in WC_Install::get_tables().
