Concurrency
This controls how many parallel operations can be performed at once. The default is 10 and can be overridden during application startup.
The 'concurrency' setting was previously in the configuration file, but is now only set at startup. The setting in the configuration file will be ignored.
To adjust the concurrency setting for the Web Service, add hms-mirror.concurrency.max-threads=n to the startup command.
hms-mirror --service --hms-mirror.concurrency.max-threads=n
To adjust the concurrency setting, use the -c|--concurrency option when starting the application.
This setting dictates the number of connections made to the various endpoints like both Hive Server 2's (LEFT and RIGHT) and the Metastore Direct connections.
