Many static type checkers have issues finding Cython's stubs.
Here is from running mypy on my current project:

error: Skipping analyzing "cython": found module but no type hints or library stubs

The same issue can be seen when using import Cython as cython:

Overview

We saw a few reported issues due to missing configs. We can add a check in DeltaLog to verify the following Spark confs.

--conf "spark.sql.extensions=io.delta.sql.DeltaSparkSessionExtension" --conf "spark.sql.catalog.spark_catalog=org.apache.spark.sql.delta.catalog.DeltaCatalog"

If these are not set, we can throw a user friendly error.

... to make it easier to read Vespa documentation on an e-reader / offline

Vespa documentation is generated using Jekyll from .md and .html files, look into options for generating the artifact as part of site generation (there might be plugins we can use here)

Use case:

Get the total duration over many events. Something like select sum(age(ended, started)) from myevents or select sum(ended - started) from myevents - depending on crate/crate#12479

See https://github.com/crate/crate/blob/dc3ce297b1597d482949a2e57479890feb3adbf4/server/src/main/java/io/crate/execution/engine/aggregation/impl/SumAggregation.java#L67

I have a simple regression task (using a LightGBMRegressor) where I want to penalize negative predictions more than positive ones. Is there a way to achieve this with the default regression LightGBM objectives (see https://lightgbm.readthedocs.io/en/latest/Parameters.html)? If not, is it somehow possible to define (many example for default LightGBM model) and pass a custom regression objective?
