Subject [jira] Commented: (HBASE-861) get with timestamp will return a value if there is a version with an earlier timestamp
Date Tue, 02 Sep 2008 21:01:45 GMT

    [ https://issues.apache.org/jira/browse/HBASE-861?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12627809#action_12627809
] 

Andrew Purtell commented on HBASE-861:
--------------------------------------

I noticed this behavior back at 0.1.0. I thought the semantics were "give me whatever is most
current for timestamp X", then backwards from there up to max_versions?

> When an explicit timestamp is specified, no results should be returned if there is no
value stored at that timestamp.
> A value should be returned (as it currently is) if the timestamp is defaulted or is LATEST_TIMESTAMP
(which is the same thing). This works correctly.
> Table name "web", columns: "contents:", "anchor:"
> store com.cnn.www/contents:/5 value = "t5"
> store com.cnn.www/anchor:my.look.ca:/8 value = "CNN.com"
> com.cnn.www/anchor:cnnsi.com/9 value = "CNN"
> get(com.cnn.www/contents:/8) should return nothing but returns value="t5", timestamp=5
> get(com.cnn.www/anchor:my.look.ca:/9) should return nothing, but returns value="CNN.com",
timestamp=8
