Riza Suminto resolved IMPALA-6311. ---------------------------------- Fix Version/s: Impala 4.5.0 Target Version: Impala 4.5.0 Resolution: Fixed > Evaluate smaller FPP for Bloom filters > -------------------------------------- > > Key: IMPALA-6311 > URL: https://issues.apache.org/jira/browse/IMPALA-6311 > Project: IMPALA > Issue Type: Task > Components: Perf Investigation > Reporter: Jim Apple > Assignee: Riza Suminto > Priority: Major > Fix For: Impala 4.5.0 > > > The Bloom filters are created by estimating the NDV and then using the FPP of > 75% to get the right size for the filter. This is may be too high to be very > useful - if our filters are currently filtering more than 75% out, then it is > only because we are overestimating NDV. -- This message was sent by Atlassian Jira (v8.20.10#820010)
