[jira] [Commented] (IMPALA-9040) Read performance improvements in
ORC support
[ https://issues.apache.org/jira/browse/IMPALA-9040?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17401503#comment-17401503 ]
Quanlong Huang commented on IMPALA-9040:
----------------------------------------
[~myloginid@gmail.com] IIRC, bloom filters will be used if we push down predicates into the ORC reader (ORC library). So IMPALA-6505 and IMPALA-10873 will cover this.
