Hi, as my understanding, in PG level, IOs are execute in a sequential way, such as the following cases:
Case 1:
Write A, Write B, Write C to the same data area in a PG --> A Committed, then B committed, then C. The final data will from write C. Impossible that mixed (A, B,C) data is in the data area.Case 2:
Write A, Write B, Read C to the same data area in a PG-> Read C will return the data from Write B, not Write A.
Are the above cases true?
thanks.
