Dear Wiki user, You have subscribed to a wiki page or wiki category on "Hadoop Wiki" for change notification.
The "Hive/IndexDev/Bitmap" page has been changed by MarquisWang. http://wiki.apache.org/hadoop/Hive/IndexDev/Bitmap?action=diff&rev1=2&rev2=3 -------------------------------------------------- For the second iteration, the first entry will be: - {{https://issues.apache.org/jira/secure/attachment/12460083/bitmap_index_2.png}} + {{https://issues.apache.org/jira/secure/attachment/12460124/bitmap_index_2.png}} This one uses 1-byte array entries, so each value in the array stores 8 rows. If an entry is 0x00 or 0xFF, it represents 1 or more consecutive bytes of zeros, (in this case 5 and 4, respectively)
