I am looking for a confirmation of understanding the log file correctly.
An user was analysing the log file and thought that the 'action' took much time:
[Kerberos logins cache timer] [INFO] [dip.krb.login.cache] - Perform routine cleanup on Kerberos logins cache (0 logins active)
In the attached log-file this line was repeated about 70 times.
However, my idea/understanding is that the actual SQL (pipeline) Query, which was fired upon the SQL server, did take approximate 6 hours to complete and during those hours, DSS does a routine check every 5 minutes, to see if the SQL Query already had any result.
Hope someone can confirm my understanding.
Thanks in advance,
As you correctly noted, DSS is simply waiting for the query to execute on the database side. Dataiku is not actually "checking every 5 minutes", it's directly waiting for the driver to return results.
The Kerberos login cache cleanup happens in a background thread and does not interfere nor slow down the query. It is instantaneous
