Can be solved by solving https://github.com/Kotlin/dataframe/issues/241. Then we can keep Java 8 but update Jupyter to 11

Hi @Ahar28, thanks for offering your help :) I was thinking that we might be missing some more conversions like from/to Instant or LocalDateTime, but on second thought, I wouldn't...

@Ahar28 did you have a chance to look at it already? We would like to have this bug fixed for 0.15.0 ideally :)

Hi! I don't think an explicit dependency on the "core" module is needed as "kotlin-spark-api" already provides it as an "api" dependency. Could you try it without? Also, currently, we're...

The specific class that is missing for you is in the [core module](https://github.com/Kotlin/kotlin-spark-api/blob/release/core/src/main/scala/org/apache/spark/sql/KotlinReflection.scala). But it should be included in your build nonetheless, so I think it's something specific to Amazon's...

Other missing functions include `size()`, `drop()`, `first()` etc. Maybe we could make it an `AnyFrame` or a `DataColumn/BaseColumn`

interestingly `.filter {}` runs on a `GroupedRowFilter`, where `T` is the original DF type. This allows type-safe access to all key columns, but also to all non-key columns which don't...

`GroupBy` has some other curiosities I found while digging into it; It has a bunch of (extension) functions for it which can be divided into three categories: 1. Functions that...

Good idea to run an [`@ExcludeFromSources`](https://github.com/Kotlin/dataframe/blob/master/KDOC_PREPROCESSING.md#excludefromsources-annotation-excluding-code-content-from-sources) check :) We will need to be careful about which documentation interfaces we can exclude though. Interfaces which users must be able to access...
