[Question] About Mini Transaction #362

Closed wangyao2016 closed 1 year ago

wangyao2016 commented 1 year ago

Describe the problem Hello, I have a question about Mini Transaction when read docs chapter Logindex. According to the document content “This causes inconsistency between the memory data structure of Page_0 and that of Page_1.” , I can't understand, what problems will be caused when ' the memory data structure inconsistency ' ? In my opinion, in pg's stand-alone mode, eg: when lsn replayed for page0 than page0 is visiable, in this case the memory data structure also inconsistency. I lack theoretical knowledge of database. I hope to get an answer. Thank you!
