# ==== Purpose ====
#
# Verify that mysqlbinlog is able to print JSON columns for row
# events correctly (NULL if the value is NULL, blob format otherwise).
#
# ==== Implementation ====
#
# Generate INSERT/UPDATE/DELETE with NULL and non-NULL values in both
# pre- and post-image. Then run mysqlbinlog to show the result.
