Andrew Purtell updated HBASE-10016: ----------------------------------- Fix Version/s: (was: 0.98.0) No patch, moving out of 0.98. Put back if you feel otherwise. > Make use of backward seek implemented in reverse scan support for range > queries. > -------------------------------------------------------------------------------- > > Key: HBASE-10016 > URL: https://issues.apache.org/jira/browse/HBASE-10016 > Project: HBase > Issue Type: Sub-task > Reporter: rajeshbabu > Assignee: rajeshbabu > > We can use backward seek in case of range queries based on value. > Example: > Lets suppose main table data as below > row1 : c > row2 : b > row3 : d > Then in index table value will be part of rowkey. > b: row2 > c :row1 > d: row3 > In this case first seek point we get from index table is row2 and next is > row1. > When the current seek point is less than previous seek point then we can use > backward seek which will be supported in HBASE-4811(Support reverse Scan) > which gives better performance than closing and reseek to the lesser rowkey. -- This message was sent by Atlassian JIRA (v6.1#6144)
