-----------------------------------------------
Summary: Allow setting of num_reactors for KuduClient
Key: IMPALA-10519
URL: https://issues.apache.org/jira/browse/IMPALA-10519
Project: IMPALA
Issue Type: Improvement
Affects Versions: Impala 4.0
Reporter: Thomas Tauber-Marshall
Assignee: Thomas Tauber-Marshall
The KuduClient allows setting a number of reactor threads, which are used for
sending rpcs to Kudu such as for scans. Impala does not currently set this
value, so it defaults to 4 threads, which may be too few for many use cases,
since there is a single KuduClient per impalad. We should determine a better
default (eg. based on the number of cpu cores) and also expose a flag to make
it configurable.
