Re: Row Lineage - implementation advice

Just curious...How can a column have multiple origins? Join key type scenarios where they have the same value regardless of where they originate from? On Feb 19, 2017 09:18, "jordan.halter...@gmail.com" < jordan.halter...@gmail.com> wrote: > You can often get the original of a column via > RelMe

Re: Thoughts on Avatica user auth?

The extra pair adds additional complexity... I think it is better to go with underlying database creds.. Or better provide a hook to interested users who want separate creds...

Re: Branches during Avatica release

It would serve like a 'marker' indicating Avatica's independence day. And that's good in certain ways - You will be able to inspect, audit from a future point, just in case if you have to. PS: Me not a calcite developer... Just a developer developing his development skills and partipating in devel

Re: Calcite design identity/new logo

I have not contributed anything towards calcite. So I have the least right to voice any opinion... But since you brought in chemistry angle, you could also consider sthg like stalactites or stalagmites (sorry if I spelt that wrong) - which are beautiful formations inside natural caves... They are b

Re: Introducing Quark - Mat. Views & Cubes across DBs

Sure..This is great. I will catch up in the first week of Feb @ Quark dev group. Thanks. It's a great news. Sometimes laziness pays ;) I mean I had wanted to do this myself. Now we have Quark and it can do the heavy lifting! Thanks!

Re: Introducing Quark - Mat. Views & Cubes across DBs

I.e. My base table is in Hive, Cube is stored in ElasticSearch. Can I now benefit from Quark? On Jan 21, 2016 10:12 PM, "Sarnath" wrote: > Yes I got that part. From my side, I have a cube built in ElasticSearch. > Can I benefit from Quark? If so, how do I interface the cube to Quark? >

Re: Introducing Quark - Mat. Views & Cubes across DBs

Yes I got that part. From my side, I have a cube built in ElasticSearch. Can I benefit from Quark? If so, how do I interface the cube to Quark?

Re: Introducing Quark - Mat. Views & Cubes across DBs

Hi Rajat, Congrats! What interfaces do you support for lattice providers? I.e. if I create a lattice, how do I benefit from your software? Best, Sarnath

Re: Jdbc server

We wrote a tech blog on our work. Interested can check here: http://www.hcltech.com/blogs/engineering-and-rd-services/olap-cubing-big-data We may rephrase few things in the blog next week. But this will give you the general direction if our approach.

Thanks. I think I have a lot to catch up. Hope will be able to do in 2nd half of this month Best, Sarnath On Nov 27, 2015 11:09 PM, "Rajat Venkatesh" wrote: > The optimizer runs in the same JVM as the JDBC code. Very similar to the > org.apache.calcite.jdbc.Driver wh

Re: Jdbc server

Hi Rajat, Good to connect with you. Good to know about your work. I did not quite understand when you said you have jdbc access through avatica but no jdbc server and a fat jar Also, we will publish a blog soon on an experiment we did. I will keep you posted on that. Good luck! Best, Sarnath

Re: Lattice, tiles and materialized views

Thanks for the link. We will definitely check that. I think we are closer to our objective of implementing a OLAP engine 0.1 than we thought earlier. Reminds me of what is written on a rear view mirror. Thanks a ton!

Re: Jdbc server

Hi Julian, Thanks for the details and thanks a lot for your time. It looks pretty simple. We will explore more and get back here if we cannot resolve it through the docs. Again, thanks a lot for your time and your help. Best, Sarnath

Re: Lattice, tiles and materialized views

see how to implement and register summary tables. Calcite is one of the most interesting project that I am recommending my colleagues to follow through. Even yesterday, we were recommending to check the Calcite-mongo connector for one of our customer's research prototype. Thanks, Best, Sarnath

Jdbc server

what are their roles are within calcite and how our project could benefit out from these. If one of you could throw some light, I would be grateful. Thanks, Best, Sarnath Best, Sarnath

Lattice, tiles and materialized views

views I don't see the connection between these and relational algebra. Can someone explain this to me, please? Thanks a ton, Best, Sarnath
