Tibor Repasi commented on CASSANDRA-16378: ------------------------------------------ Thank you [~e.dimitrova], I've cherry picked your commit [be699f|https://github.com/apache/cassandra/commit/ab9fcbaf998fb584ae84d584c298af63fcbe699f] just partly, to not duplicate the entry in CHANGES.txt. Squashed and rebased onto trunk. Doc update ticket is open at CASSANDRA-17344. > Expose application_name and application_version in virtual table > system_views.clients > ------------------------------------------------------------------------------------- > > Key: CASSANDRA-16378 > URL: https://issues.apache.org/jira/browse/CASSANDRA-16378 > Project: Cassandra > Issue Type: Improvement > Components: Feature/Virtual Tables > Reporter: Tibor Repasi > Assignee: Tibor Repasi > Priority: Normal > Labels: AdventCalendar2021, gsoc2021, lhf, mentor > Time Spent: 2h 50m > Remaining Estimate: 0h > > Recent java-driver's > [com.datastax.oss.driver.api.core.session.SessionBuilder|https://docs.datastax.com/en/drivers/java/4.9/com/datastax/oss/driver/api/core/session/SessionBuilder.html] > respects properties > [ApplicationName|https://docs.datastax.com/en/drivers/java/4.9/com/datastax/oss/driver/api/core/session/SessionBuilder.html#withApplicationName-java.lang.String-] > and > [ApplicationVersion|https://docs.datastax.com/en/drivers/java/4.9/com/datastax/oss/driver/api/core/session/SessionBuilder.html#withApplicationVersion-java.lang.String-]. > It would be helpful to expose this information via virtual table > {{system_views.clients}} and with {{{}nodetool clientstats{}}}. > +Additional information for newcomers:+ > The drivers can send as part of the {{STARTUP MESSAGE}} the > {{APPLICATION_NAME}} and {{APPLICATION_VERSION}} options. Two new volatile > fields {{applicationName}} and {{applicationVersion}} need to be added to > {{ClientState}} in a similar way to {{driverName}} and {{{}driverVersion{}}}. > The {{APPLICATION_NAME}} and {{APPLICATION_VERSION}} options need to be > retrieved in {{StartupMessage#execute}} and passed to the > {{{}ClientState{}}}. > The new {{application_name}} and {{application_version}} columns need to be > added to the {{system_views.clients}} represented by the {{ClientsTable}} > class. The data then need to be retrieved from the {{ClientState}} through > {{{}ConnectedClient{}}}. > Some unit tests similat to {{SettingsTableTest}} should be added. -- This message was sent by Atlassian Jira (v8.20.1#820001) --------------------------------------------------------------------- To unsubscribe, e-mail: commits-unsubscr...@cassandra.apache.org For additional commands, e-mail: commits-h...@cassandra.apache.org
