Hi Bertil,
Let me explain a bit about Drill and Calcite. Drill uses Calcite for query
planning. Until fairly recently, Drill had a fork of Calcite that had some
special features which Drill required. However, about 1-2 versions ago, we
were able to get Drill off of the fork an onto "mainstr
Hi Jia,
Thanks for your interest! I'd be happy to work with you to build out a Drill
<> Sedona collab. This sounds really interesting and I think would be a great
addition to both projects.
With that said, I'm totally unfamiliar with Sedona unfortunately, so I'm not
sure how much help I can b

That would be great. You are welcome to add Drill in the wiki page at [1].
A while ago, I started work on a collection of UDFs for interacting

No offence taken on my side ;-)
Do you think sedona-common could broaden its scope to non cluster technologies?
In Baremaps, we assumed that a few TBs of vector data can now easily be
processed efficiently on a single node with a lot of RAM and NVMe SSDs. Our
current implementation uses Postgis
Hi all (removing non-geospatial projects from the loop),
Just to clarify about the mission of the Apache Sedona project and make
sure nobody gets offended by my words before :-)
First of all, sedona-common is not a replacement of JTS at all. I also
contribute to JTS. Instead, sedona-common is mor

This may be related to the version of calcite used by Flink (1.32) [1
Hi Bertil,
This is awesome. However, although Flink depends on Calcite, the
SpatialType does not seem to be supported by Flink (based on my test
last year). Not sure if this works for Drill. Please correct me if I'm
wrong.
On a side note, why don't we implement all geometric computation
logics in
Hello Jia and Charles,
I'm really interested in this topic as well. Apache Calcite transitionned from
ESRI Geometry to JTS, and many ST functions have been implemented there as well
[1, 2, 3]. Sharing experiences and code could benefit all projects.
I haven’t looked into the details of each pro
Hi Charles,
This is Jia Yu from Apache Sedona. I think what you did is fantastic.
As a project of this Joint codespring, I am proposing to implement a
comprehensive set of spatial functions to Apache Drill using Apache
Sedona.
Apache Sedona has implemented over 130 ST functions and a

Hi Martin,
Thanks for sending. I'd love for Drill to be included in this. I have a
question for you. A while ago, I started work on a collection of UDFs for
interacting with H3 Geo Indexes. I'm not an expert on this but would this be
useful? Here's the repo: https://github.com/datadistillr
