So at the end of each read_row, the server copies BLOB data from the engine's buffer to its own? This seems a bit odd (because each BLOB requires a memcpy that could potentially be avoided). However, if it does work this way, it makes things a lot easier from the storage engine's point of view. Regards, - Slava
