 ## Why database need to be changed?
 
-The new schema is proposed to use additional table as a replacement for the use of wp_postmeta for storing additional data used by forums, topics and replies. Database queries that need to join with the data in the wp_postmeta are very slow because join in the SQL is made on the meta_value column (type is LONGTEXT). This column can't be indexed, and it requires casting to get proper data format, and that makes SQL queries execution very slow.

 The speed of bbPress queries that depend on the wp_postmeta joining is not critical issue for small forums, but with larger number of topics and replies, it can considerably slowdown the website for more complex queries.
 
 Without these changes, bbPress can't scale well to large forums that run complex queries or have features that need better filtering, search and other things that use complex queries.
 
 ## Which new tables are needed?
 
-This proposition currently includes 3 tables for forums, topics and replies, 2 tables for topics and forums subscriptions and 1 table for favorite topics.

 Tables for forums, topics and replies are made to replicate data saved into wp_postmeta table. Each column in these tables corresponds to the meta field stored in the wp_postmeta table. All ID based columns are indexed to make required joins very fast. Proper data types are used for all columns.
