@ -2308,8 +2308,15 @@ static int start_transaction(MYSQL *mysql_con, my_bool consistent_read_now)
We use BEGIN for old servers. --single-transaction --master-data will fail
on old servers, but that's ok as it was already silently broken (it didn't
do a consistent read, so better tell people frankly, with the error).
We want the first consistent read to be used for all tables to dump so we
need the REPEATABLE READ level (not anything lower, for example READ
COMMITTED would give one new consistent read per dumped table).
