Re: [DICUSS] Support building physical RelNode in Calcite

Thanks Xiening for moving this to dev list. Unlike logical operators, with which many systems share the same structure, physical operators are pretty implementation dependent. RelBuilder provides the common interface to create aggregate, join. But what kind of physical aggregate? HashAgg,

[DICUSS] Support building physical RelNode in Calcite

Hi all, In light of CALCITE-2970, I’d like to initiate a discussion. Currently the framework itself does not have a way to create physical RelNode (RelNode with a particular convention). We completely rely on adapter rules to convert logical nodes into physical ones. There are a few major

Re: Rel as a service

Andrii, You mentioned that "optimizations that happen during SQL-to-Rel conversion": > One thing to consider is there are some optimizations that happen during > SQL-to-Rel conversion, so you won't get those if you use RelBuilder > directly. I'd like to minimize these.

Re: JMH dependency vs licensing

>no longer publish the ubenchmark jar to nexus We could resume publishing benchmark jar, however, it embeds third-party code, so it requires to compose the license file. I have chosen to skip the publication as a trivial escape hatch. Have you used ubenchmark.jar previously? It would be great if

Re: Rel as a service

Thanks for sharing this Michael. Interesting read. The approach that they followed seems like what I had in mind as an "easy" solution. "Calcite is a Java project, so integration with C++ isn't entirely trivial. Fortunately, we can serialize the relational algebra it outputs to JSON and use this

Re: JMH dependency vs licensing

Hello, As of release 1.22.0, we no longer publish the ubenchmark jar to nexus and (I guess as consequence) neither to maven central. Initially, I was a bit surprised but apparently it is related to this thread and LEGAL-399 [1] so it seems normal. I am bringing this up just to avoid that other

Building a Calcite Adapter

Hi Calcite Devs, Firstly, thank you to all of you for building this fantastic tool. I'm currently experimenting with using Calcite on top of our document database Crux (opencrux.com) offering bitemporal features using a Datalog query language. You can see our efforts here, written in Clojure!

Re: Rel as a service

There's not much detail, but the blog post below[0] discusses how MapD integrated Calcite with their C++ code. At least some of their is open source[1]. [0] https://www.omnisci.com/blog/fast-and-flexible-query-analysis-at-mapd-with-apache-calcite-2 [1] https://github.com/omnisci/omniscidb --

Re: Rel as a service

Hi Tal, Although our case is not really similar to yours, we had to do a conversion from our custom API to Calcite RelNodes. We just used RelBuilder to build the tree, and then optimized and executed it. I would say there is nothing really difficult, most of that logic could be found in Calcite
