Hi Sage, I am now working with the BP osd: update Transaction encoding, but the Transaction::get_data_alignment make me confused. This method give the alignment which is used by FileJournal to do better buffer build. It calculate the alignment by largest_data_off and get_data_offset() while the first is an offset of some object and the second is an offset of the transaction encode result. I am not sure there is any reason to do calculation between them. The code works fine, probably because any result is fine for Transaction::get_data_alignment, while FileJournal::prepare_single_write can use any alignment value to build logical bufferlist. Can you give me some explanation? Thank you. -- Dong Yuan UnitedStack Room 302, Block C, Building. 4, Zongguancun Software Park, 100193 Haidian Dist. Beijing.
