Hi,
As part of my research project, we would like to use the stored
procedure. do you have any pointers for the implementation of stored
procedures or any alternatives in Calcite?
Thanks and Regards

Hi,
Can anyone explain to me what is the advantage of Filterable Table? How
can we efficiently make use of that in a Federated system?

Hi Stamatis,
Thanks a lot for the quick response and support. I think, now I can
give an overview of the cost model used in calcite to my other group
members. ,
Thanks and Regards

Is this correct? to compare the cost records in Calcite?

connecting
calcite across multiple systems, then 'i/o' should be greater than '0.0',
right? Because it needs to read the results from the push-down operations?
Can you please explain these in a bit more detail? I appreciate your
support and suggestions.

Hi,
I would like to know about the Calcite CBO in detail, including how it
deals with global optimization when multiple processing systems are
associated with it. Any documentation, pointers are much appreciated.
Thanks and Regards

to contribute towards the benchmark analysis for
Calcite.
The JMH benchmark test for TPC-H and the results of its comparison with
postgres is also attached to this email. Please find them and I appreciate
your feedback in this regard.
Thanking you

Hi Julian,
Thanks for a lot for the prompt response and support. I will try running
the test with JMH and will let you know the feedback.
I wish you all have a prosperous new year.
Thanks and Regards

bility. But, if I
fail to give a good case study in favour of Calcite, I am afraid that I
could loose an opportunity to work with calcite.
