Try pushing your key to the GNU, MIT and Ubuntu servers: gpg --send-keys KEY_ID #GNU gpg --keyserver pgp.mit.edu --send-keys KEY_ID #MIT gpg --keyserver keyserver.ubuntu.com --send-keys KEY_ID #Ubuntu After pushing your keys, check that they are sent to the server by searching for your key

I did not know this is how it works, I just copied the example above. Would there be an easy way to create a RelNode containg a tablescan over the materialized view "mv"? Trying to create one using for instance a relbuilder gives a calcite exception. Otherwise I might just look for another test

bq . Since we are talking about materialized views, I think in most cases tableRel should be simply a LogicalTableScan. Stamatis is correct about this, I had not realized tableRel == queryRel in your sample code. Thanks, Jesús On Fri, May 3, 2019 at 6:12 AM Stamatis Zampetakis wrote: > I

Apologies for the confusion. If there is still interest, I can participate again next week on http://tiny.cc/mku45y. We can also change the time to +/- 3 hours if that is more convenient for other people. @Haisheng: I have an issue with pgp.mit.edu keyserver (it seems to be down) so I cannot

Hi Ivan, It sounds like an interesting project, and I think Calcite will definitely help you get there. However your questions are quite broad so it is difficult to provide a concrete answer. The best place to get started is the official website [1] where there are a lot of examples and

Re: ClassCastException RelOptCostImpl VolcanoCost while using HepPlanner

I think the main problem comes from the fact that tableRel == queryRel in the test case you provided. Defining the materialized view like that basically says that when you find a part of the query that satisfies queryRel replace it with itself. In conjunction with the rule that is used, which

Dear Jesus, I think your intuition in this regard is correct. After executing the main program in the HepPlanner the resulting plan contains a lot of circular references. Changing the matching order does not influence this behaviour. Mark On Thu, 2 May 2019 at 22:14, Jesus Camacho Rodriguez
