[jira] [Commented] (HBASE-10354) Add an API for defining consistency per request

    [ https://issues.apache.org/jira/browse/HBASE-10354?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13872920#comment-13872920 ]

bq. It is more like a "timeline consistency" rather than the eventual consistency a-la dynamo.
Let us call it 'timeline consistency' from here on out then while it still in the inception phase. Let us not allow 'eventually consistent' anywhere near our lexicon else we will only confuse.

> We should add an API to be able to define the expected consistency level per operation. This API should also allow to check whether the results coming from a query (get or scan) is stale or not. The defaults should reflect the current semantics.
