Hi, Extremely sorry for the delayed response!
Basically , I am experimenting an Apache Solr plugin for Drill and tried to use Tableau. On intial selection of a "Table" , I see these queries from drill webui profile SELECT * FROM (SELECT * FROM `solr`.`CSVStringData`) T LIMIT 0 SELECT * FROM (SELECT SUM(1) AS `COL` FROM `solr`.`CSVStringData` `CSVStringData` HAVING COUNT(1)>0) T LIMIT 0 I have a dataset of 2,297,451,8 and when I try access that,the tableau screen in kind of stuck in "Processing Request" for 5 minutes.

Do you have the actual full query that is being generated? Tableau has a number of customization features, wonder if it is possible to optimize those settings to avoid this issue. --Andries > On Feb 19, 2016, at 10:16 AM, Sudip Mukherjee <smukher...@commvault.com> > wrote: > > Hi, > > Have anyone tried optimizing SUM(1) query in drill?
