Did you have considered the other comments? Related to putting the file offset into the pages message reference? This would avoid to creating the Map<Integer,Integer> For the created page reference, we can record the file offset which can be used to seek and read file if message is removed by gc. But for the message not yet depaged or not committed in a page transaction, how do we read message and create reference just according to page number and message number?
