# MDEV-33044 Loading time zones does not work with alter_algorithm INPLACE

set global alter_algorithm=INPLACE;

# Because loading timezones alters the mysql tables,
# this test will leave mysql in a different state than when it started.
# Furthermore, checksums on the various mysql.timezone_x tables will fail. 

# Therefore we:
# 1. Make "backups" of the existing tables by renaming them
# 2. Make dummy clones of the tables we just backed up
# 3. Load timezones with alterations made to the dummy clone tables
# 4. Drop the newly made tables with changes made to them
# 5. Restore the backed up tables so the checksums will pass
