# **NOTE** Joins for this grammar are currently not working as intended.
# For example, if we have tables 1, 2, and 3, we end up with ON conditions that
# only involve tables 2 and 3.
# This will be fixed, but initial attempts at altering this had a negative
# impact on the coverage the test was providing. To be fixed when scheduling
# permits. We are still seeing significant coverage with the grammar as-is.

# partition_pruning.yy
#
# Purpose: RQG grammar for testing partitioning by COLUMN_LIST
# , introduced in WL#3352
#
# NOTES: * Must be used with conf/partition_pruning.zz as the gendata
# configuration file
# * Designed for:
# ** server-server comparisons, particularly
# comparing a version of MySQL without partitioning
# (like 5.0) to one that has partition_pruning
# ** valgrind runs
# ** Single-server stress / endurance testing
#
# * Will NOT work if the server has partitioning, but
# not partitioning by COLUMN_LIST and
# * Basically, the grammar was designed to ensure
# that no result-set differences occur via the
# server-server compare and to look for crashes
# and memory leaks
# * the gendata file, conf/partition_pruning.zz
# contains the table setups / partitioning schemes
