It is because the default filter in Yourkit skip the “org.apache” packages :-)
To change the filter: click “settings” -> “filters” and click out the
“org.apache”. Enjoy profiling apache code then!

Based on the described example, it seems possible to implement it in one job by
using MToNPartitioningConnectorDescriptor.
You can force that merge-BF-operator only runs in one partition by using
PartitionConstraintHelper.addAbsoluteLocationConstraint() function.

Hi, I want to pick up this thread to verify if the AQL will still be supported
in the future?
Currently, Cloudberry automatically translates the JSON request to AQL
statements. It will be a hard work to switch to SQL++.
I’m not object to set the default option to SQL++. However, we will keep t
@Yingyi, I’m not saying learning SQL++ is difficult.
Currently, we have a class called AQLGenerator that can translate the
Cloudberry request syntax to AQL. It took us several weeks finishing it.
I guess it will take similar time to write a SQLPPGenerator to achieve the same
goal.
As long as
expert on JDBC. Do you think it’s a good
project? and will anyone interested in give the detailed instruction on it?
Otherwise, I will close this issue to give it a very low priority.

Right now, the same link returns a following error.
page can’t be found
I’m wondering what is the new path to get the same information? Thanks!

I also observe this getting slower problem every-time when we re-ingest the
twitter data. One difference is that the duplicate key could happen, and we
know that is indeed duplicate record. To skip the search, we would expect an
“upsert” logic ( just replace the old one :-) ) instead of an inse
