Zain Humayun created CALCITE-1853: ------------------------------------- Summary: Push Count distinct into Druid when approximate results are acceptable Key: CALCITE-1853 URL: https://issues.apache.org/jira/browse/CALCITE-1853 Project: Calcite Issue Type: Bug Components: druid Reporter: Zain Humayun Assignee: Zain Humayun
Currently queries such as {code:sql} select count(distinct "dimension") from "table"; {code} are not pushed into Druid using the cardinality aggregator because it produces an approximate result. There exists a JDBC string parameter called {{approximateDistinctCount}} introduced in CALCITE-1587 that lets the user specify whether approximate results are acceptable in count distinct queries, however this parameter is not currently utilized by the Druid adapter. -- This message was sent by Atlassian JIRA (v6.4.14#64029)
