Subject [jira] Commented: (CASSANDRA-1978) get_range_slices: allow key and token to be interoperable
Date Wed, 26 Jan 2011 15:55:44 GMT

    [ https://issues.apache.org/jira/browse/CASSANDRA-1978?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12987068#action_12987068
] 

Jonathan Ellis commented on CASSANDRA-1978:
-------------------------------------------

Commented originally on CASSANDRA-2003, but really belongs here:

Let's tighten up ThriftValidation to re-disallow ambiguous queries, e.g., all four of {start_key,
start_token, end_key, end_token}.

Also, please don't change whitespace on lines that are otherwise unchanged, especially when
the change takes us farther from the existing style (e.g., we use a single space around equal
signs, and do not align them with others).

> problem: get_range_slices requires two keys or two tokens, so we can't walk a randomly
partitioned cluster by token.
> solution: allow keys and tokens to be mixed.  however, if one side is a token, promote
the bounds to a dht.Range, instead of a dht.Bounds.
