This patch adds the ability to store extra field metadata in the table map event. This data can include pack_length() or field_lenght() for fields such as CHAR or VARCHAR enabling developers to add code that can check for compatibilty between master and slave columns. More importantly, the extra field metadata can be used to store data from the master correctly should a VARCHAR field on the master be <= 255 bytes while the same field on the slave is > 255 bytes. The patch also includes the needed changes to unpack to ensure that data which is smaller on the master can be unpacked correctly on the slave. WL#3915 : (NDB) master's cols > slave Slave starts accepting and handling rows of master's tables which have more columns. The most important part of implementation is how to caclulate the amount of bytes to skip for unknown by slave column. |
