Subject [jira] [Commented] (CASSANDRA-2704) provide a typed key value for returned rows via JDBC
Date Thu, 26 May 2011 17:17:47 GMT

    [ https://issues.apache.org/jira/browse/CASSANDRA-2704?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13039795#comment-13039795

Jonathan Ellis commented on CASSANDRA-2704:
-------------------------------------------

bq. You may want to get all the metrics since the start of the month for 3 entities to compare
them. 

IMO this kind of pseudo-analytics should be 3 calls.  (Under the hood of course it's the same
amount of work either way.)

> o.a.c.c.jdbc.CassandraResultSet provides access to column values as Cassandra type aware
via the TypedColumn. But it only provides a byte[] for the key. It would be handy to have
a TypedKey class that does the same but for the key.
> This would be handy when doing a multi SELECT as the server only returns rows we have
columns for.
