    [ https://issues.apache.org/jira/browse/HBASE-3005?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12910054#action_12910054 ] 

Kannan Muthukkaruppan commented on HBASE-3005:
----------------------------------------------

Note: This applies when we use the TimestampsFilter() to fetch a specified set of versions.

Patch looks good to me. Jonathan/Ryan: please review/approve. Thanks.

> Skip between timestamps to avoid the unnecessary read for all the blocks which come in between.
> For example:
> If we have timestamps from 1 to 1000 for a particular row, family, qualifier and we want to read only timestamps 990 and 10, then we should be able to read 990 and then jump to 10 instead of doing a sequential read including everything in between.
