Subject Re: [ANNOUNCE] Phoenix 1.2 is now available
Date Thu, 16 May 2013 21:02:44 GMT
Hi James,

You have mentioned support for TopN query. Can you provide me HBase Jira
ticket for that. I am also doing similar stuff in
https://issues.apache.org/jira/browse/HBASE-7474. I am interested in
knowing the details about that implementation.

Thanks,
Anil Gupta
