# ==== Purpose ====
#
# check replication of load data with the server parameters subjected to
# read_buffer_size > max_allowed_packet
#
# ==== Implementation ====
#
# Insert many rows into t1, write t1 to file.
# Load the file into t2.
# See that t2 came out as expected on slave.
#
# ==== Related Bugs ====
#
# BUG#30435 loading large LOAD DATA INFILE breaks slave with
# read_buffer_size set on master
# BUG#33413 show binlog events fails if binlog has event size of close
# to max_allowed_packet

# We turn off binlogging to avoid too much noise in the binlog. t1 is
# just an auxiliary construction anyways, it is not needed on the
# slave.
