Change subject: IMPALA-9207: [DOCS] Documented the #Inst in exec summary ...................................................................... Patch Set 1: (2 comments) Found a few more occurrences of a summary query when I grepped on "#Hosts": * docs/topics/impala_mem_limit.xml * docs/topics/impala_live_summary.xml should also be updated. http://gerrit.cloudera.org:8080/#/c/14860/1/docs/topics/impala_explain_plan.xml File docs/topics/impala_explain_plan.xml: http://gerrit.cloudera.org:8080/#/c/14860/1/docs/topics/impala_explain_plan.xml@147 PS1, Line 147: When the <codeph>MT_DOP</codeph> query option is set to a value larger than : <codeph>0</codeph>, <codeph>#Inst</codeph> column in the output shows the number of : fragment instances. Impala decomposes each query into smaller units of work that are : distributed across the cluster, and these units are referred as fragments. The #Inst column in the output will be also shown when MT_DOP=0, with the same value as #Hosts, since there will be exactly one fragment for each host. (Might be good to clarify, here or at the example.) http://gerrit.cloudera.org:8080/#/c/14860/1/docs/topics/impala_explain_plan.xml@168 PS1, Line 168: 0 This and the zeros below should be ones. -- To view, visit http://gerrit.cloudera.org:8080/14860 To unsubscribe, visit http://gerrit.cloudera.org:8080/settings Gerrit-Project: Impala-ASF Gerrit-Branch: master Gerrit-MessageType: comment Gerrit-Change-Id: I938930c66144ba6bce766981d363abe4b28ba524 Gerrit-Change-Number: 14860 Gerrit-PatchSet: 1 Gerrit-Owner: Alex Rodoni <[email protected]> Gerrit-Reviewer: Alex Rodoni <[email protected]> Gerrit-Reviewer: Impala Public Jenkins <[email protected]> Gerrit-Reviewer: Norbert Luksa <[email protected]> Gerrit-Comment-Date: Fri, 06 Dec 2019 12:23:36 +0000 Gerrit-HasComments: Yes
