Update:

To be clear, the main reasons I put the man page table in a different database was to make the main database smaller (75%) smaller; and so the daily backups are faster and use less resources. These backups take up less disk space on both the main server and the backup server.

From a DB CPU perspective, there is little to no performance difference having one huge database or two smaller ones.

NAME
ndb_drop_table - drop an NDB table SYNOPSIS
ndb_drop_table options DESCRIPTION
ndb_drop_table drops the specified NDB table. (If you try to use this on a table created with a storage engine other than NDB, the attempt fails with the error 723: No such table exists.) This operation is extremely fast; in some cases, it can be an order of magnitude faster than using a MySQL DROP TABLE statement on an NDB table. Usage ndb_drop_table -c connect_string tbl_name -d db_name The following table includes options that are specific to ndb_drop_table. Additional descriptions follow the table. For options common to most MySQL Cluster programs (including ndb_drop_table), see Options Common to MySQL Cluster Programs(1).
