There is not much we can do here other than fetching only partially filled partitions using the API introduced in HIVE-19715. For partitions which are found to be updated, we will need to do a full partition fetch. Other than that I think we should profile this on a large sized table to identify how much of a hit this causes over the regular refresh table command. -- To view, visit http://gerrit.cloudera.org:8080/16308 To unsubscribe, visit http://gerrit.cloudera.org:8080/settings Gerrit-Project: Impala-ASF Gerrit-Branch: master Gerrit-MessageType: comment Gerrit-Change-Id: I50e8680509f4eb0712e7bb3de44df5f2952179af Gerrit-Change-Number: 16308 Gerrit-PatchSet: 2 Gerrit-Owner: Vihang Karajgaonkar <[email protected]> Gerrit-Reviewer: Impala Public Jenkins <[email protected]> Gerrit-Reviewer: Quanlong Huang <[email protected]> Gerrit-Reviewer: Tim Armstrong <[email protected]> Gerrit-Reviewer: Vihang Karajgaonkar <[email protected]> Gerrit-Comment-Date: Mon, 10 Aug 2020 21:10:40 +0000 Gerrit-HasComments: No
