--echo # TEST 2
--echo # Greedy search iteration test for chain of tables
--echo #

--source include/greedy_search_load_tables.inc

# Explanation to the test
#
# A chain of tables is joined like this:
#    t1 JOIN t2 ON t1.<some_col>=t2.<some_col> JOIN t3 ON ...
#
# Different variants of table sizes and columns in the join conditions
# are tested. 
#
# The column names mean:
#   'pk'     - The column is primary key
#   'colidx' - The column is indexed
#   'col'    - The column is not indexed
#
# The table names mean:
#   tx_y     - table with x rows, y is simply used to get unique table names
#
# A comment explains each test. The notation used is
#    (...,tx_col_next):(ty_col_prev,...)
# which means that table x is joined with table y with join condition
# "ON tx.col_next = ty.col_prev" like this:
#    t1 JOIN t2 ON t1.col_next=t2.col_prev ...
