Re: [DISCUSS] Towards Cascades Optimizer

Hi all, As planned in my proposal, I opened the pull request [1] for CALCITE-3896 to achieve: 1. Top-down trait request 2. Bottom-up trait derivation 3. Trait enforcement without AbstractConverter The feature can be turned on or off by a flag, either through property config file or

Re: [DISCUSS] Towards Cascades Optimizer

If your test cases are SQL scripts, it might be fairly straightforward to port them to Quidem (.iq) files. Plenty of examples in https://github.com/apache/calcite/tree/master/core/src/test/resources/sql . Quidem files

Re: [DISCUSS] Deprecate grouped window functions

Polymorphic table function is logged at [1]. I assigned that to myself because I started to implement DESCRIPTOR (a part of PTF in SQL standard). It's very welcomed if anyone wants to help to accelerate the implementation. (But please use another thread to discuss it). Back to this thread's

Congratulations and welcome, Forward! Thank you for your contributions. It would be great to add TBDS (and its logo) to the “powered by” page[1]. What do you think? Julian [1] https://calcite.apache.org/docs/powered_by.html > On Apr 29, 2020,

Re: [ANNOUNCE] New committer: Wang Yanlin

Welcome, Yanlin! Thanks for your contributions so far, and thanks for introducing yourself. I often learn so much from committers’ self-introductions about how Calcite is being used. I know we have other Alibaba-related projects on the “powered by” page [1] (Flink/Ververica, MaxCompute) but

Welcome Jin! Thanks for your contributions so far, looking forward to more! Are you on the MaxCompute project? It’s already on our “powered by” page[1], so I think people are familiar with it. Julian [1] https://calcite.apache.org/docs/powered_by.html#alibaba-maxcompute

Re: [DISCUSS] Deprecate grouped window functions

I understand that you need to continue to support the SQL syntax while your users still want it. I suggest that Calcite continues to support the SQL syntax in the parser (and the SqlNode AST) but deprecates and removes the support in the algebra (RelNode) within one or two releases (3 - 6

Re: Building a Calcite Adapter

We went down the route of wrapping Calcite with our own JDBC driver that strips out the `VALIDTIME AS OF (...)` from ``VALIDTIME AS OF (...) SELECT * FROM FOO`. We do this by overriding CalcitePrepareImpl and adding internalParameters to the CalciteSignature, that our enumerator then uses when

What is the status of polymorphic table functions? We'd like to use them. Viliam On Thu, 30 Apr 2020 at 16:16, Timo Walther wrote: > Thanks for considering our needs. > > I'm pretty sure that windows are in almost every streaming pipeline with > aggregations. Unlike regular Java API, SQL

Re: [DISCUSS] Deprecate grouped window functions

Thanks for considering our needs. I'm pretty sure that windows are in almost every streaming pipeline with aggregations. Unlike regular Java API, SQL syntax is very difficult to deprecate. We usually give Flink user 1-2 releases time to update their code. Once Calcite supports polymorphic

Re: [DISCUSS] Towards Cascades Optimizer

Sure. I will add more cases to my PR. I did not design more cases because our own product has a test frameworks, which contains thousands of actual user queries. Calcite's code base is quite different. I cannot just migrate cases to calcite. So it may take some time. On Wed, Apr 29, 2020 at
