# This test upgrades metadata of a large number of tables which have the following
# structure:
#
# CREATE TABLE t1 (
#   col1 int(20) unsigned NOT NULL AUTO_INCREMENT,
#   col2 varchar(255) DEFAULT NULL,
#   col3 varchar(255) DEFAULT NULL,
#   col4 bigint(20) unsigned NOT NULL,
#   col5 varchar(20) DEFAULT NULL,
#   col6 tinyint(1) unsigned NOT NULL,
#   col7 tinyint(1) unsigned DEFAULT NULL,
#   col8 varchar(255) DEFAULT NULL,
#   col9 int(11) unsigned DEFAULT NULL,
#   col10 varchar(255) DEFAULT NULL,
#   col11 varchar(255) DEFAULT NULL,
#   col12 varchar(255) DEFAULT NULL,
#   col13 bigint(20) unsigned DEFAULT NULL,
#   col14 varchar(255) DEFAULT NULL,
#   col15 varchar(20) DEFAULT NULL,
#   col16 bigint(20) unsigned DEFAULT NULL,
#   col17 decimal(10,5) NOT NULL,
#   col18 decimal(10,5) NOT NULL,
#   col19 decimal(10,5) NOT NULL,
#   col20 float(7,2) NOT NULL,
#   PRIMARY KEY (col1)
#   ) CHARACTER SET=latin1 ENGINE=ndbcluster;
#
# The number of tables being restored (and upgraded) are configurable and controlled by the db_number variable.
# By default, db_number=1 which results in 100 tables i.e. `t1` to `t100` created in the `db1` database which
# are restored and upgraded. The number of tables being upgraded can be increased by multiples of 100 by adjusting
# the db_number variable. For example, setting db_number to 10 creates databases `db1` to `db10` and a total of
# 1000 (db_number*100) tables are upgraded. This somewhat convoluted test design is to ensure that this test can
# be run without issues in PB2 while also providing coverage of a larger upgrade scenario when run manually with a
# few tweaks in the test and its corresponding .cnf file.
