With big tables, there might be performance problems and sometimes it might result in This option is used to have better memory usage by the JDBC driver and, in the case of MySQL, to quicken the transfer of large data sets. It is recommended to set this option to However, such connections should be used only for reading data, since enabling streaming breaks the normal transactional behaviour |
