摘要:
Disclosed herein are system, method, and computer program product embodiments for determining row visibility states. An embodiment operates by initializing a result bitmap for rows based on visible row state values of row state bitmaps corresponding to the rows, wherein values of the result bitmap indicate whether the row are visible or not visible; determining one or more rows whose corresponding visible row state values indicate that the one or more rows are not visible; and determining whether to update the result bitmap to indicate that the one or more rows are visible based on one or more versioned row state values, wherein the one or more versioned row state values indicate whether the corresponding rows are not visible or possibly visible.
