Impala Best Practices
The Impala Best Practices page contains charts that include description of each best practice and how to determine if it is being followed.
To open the Impala Best Practices page, click the Best Practices tab on the Impala service page. See the Impala documentation for more detail on each best practice and for additional best practices.
Adjust the time range to see data on queries run at different times.
Click the charts to get more detail on individual queries. Use the
filter box at the top right of the Best Practices page to adjust which
data is shown on the page. For example, to see just the queries that
took more than ten seconds, make the filter query_duration >
10s
.
Create a trigger based on any best practice by choosing Create Trigger from the individual chart drop-down menu.
