[jira] [Commented] (PIG-4550) HBaseStorage, return timestamp of
cell stored in HBase
[ https://issues.apache.org/jira/browse/PIG-4550?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14542845#comment-14542845 ]
Brian Johnson commented on PIG-4550:
------------------------------------
I think that will be too easily confused with includeTimestamp. I think it would be better to use includeTimestamp in the read and put it after the rowkey to make it consistent with the store.

> Key: PIG-4550
> URL: https://issues.apache.org/jira/browse/PIG-4550
> Project: Pig
> Issue Type: Improvement
> Affects Versions: 0.12.0
> Environment: HBaseStorage, HBase
> Reporter: Sergey
> Assignee: Sergey
> Priority: Minor
>
> HBase implicitly stores timestamp for each cell. Sometimes this feature is used to track historical data. I would like to provide option for HBaseStorage which would return cell timestamp in milliseconds
> Interface:
> add option "withTimestamp" to HBaseStorage constructor
> Implementation:
> add timestamp:long as last element of tuple.
> RFC.
