Re: Benchmarking Calcite - starting the conversation on the targets and design of the benchmark

One interesting exercise would also be to pick a popular benchmark (e.g. TPC-H) and just look at the plan produced by Calcite vs existing RDBMS optimizers (e.g. Postgres, MySQL). Along with performance analysis of the various options, it seems there's a paper in there. -- Michael Mior

Re: Support for SQL for Multi-dimensional Arrays

AFAIK, there's no current or planned support but this does seem like valuable addition. It would be great step towards having a MonetDB or SciDB adapter in the future. I would suggest logging a JIRA so we can discuss further. -- Michael Mior mm...@apache.org 2018-02-03 21:27 GMT-05:00 Edmon

Re: Benchmarking Calcite - starting the conversation on the targets and design of the benchmark

Note that Calcite has a “plus” module which is a place to add other data sets (e.g. TPC-H, TPD-DS) and tests and benchmarks based on them. Also the “ubenchmark” module for micro-benchmarks. I don’t know whether the work you are planning would be a natural fit within these modules. > On Feb 5,

Re: Benchmarking Calcite - starting the conversation on the targets and design of the benchmark

I am going to create two JIRA issues: 1. Development of the benchmark for Calcite. 2. An R development focused on benchmarking, performance evaluation, and a study. Thank you, Edmon On Mon, Feb 5, 2018 at 9:26 AM, Michael Mior wrote: > One interesting exercise would also

Re: Benchmarking Calcite - starting the conversation on the targets and design of the benchmark

I would think that a TPC-DS benchmark would be more appropriate for the type of queries I'd be interested in working with Calcite. Also as an end result of these efforts I would imagine the community would get better instrumentation of metrics up and down the query processing pipeline. From

Re: Support for SQL for Multi-dimensional Arrays

Do you have a draft or a summary of Part 15? Part 15 (SQL/MM) is a really new part of the standard - so new that it wasn’t in the 2014 draft of the SQL standard that I generally use. It would be great to support multi-dimensional arrays, but it would help if there was something in the open so

This error generally occurs when too much memory is being used. I don't think there's anything we can do besides look at what tests are eating up memory and trying to pare that down somehow. -- Michael Mior mm...@apache.org 2018-02-05 20:43 GMT-05:00 Shuyi Chen : > I've

Re: Benchmarking Calcite - starting the conversation on the targets and design of the benchmark

I think that "plus" is a good starting point for a general benchmark, and then "ubenchmark" maybe for fine-grained profiling of the sub-components such as planner, etc.. On Mon, Feb 5, 2018 at 8:08 PM, Julian Hyde wrote: > Note that Calcite has a “plus” module which is a place

Re: Adjust clacite to support kylin query

If the query requires more than one data source (Kylin and something else) then a logical plan is necessary. If it’s just Kylin then what you suggest would work in principle, but it would be hard to make it work in practice. It might be simpler to fix the SQL generated by Calcite’s JDBC adapter
