Sorry for the delays @michelheil - right now we're in the middle of refactoring for 1.0; once we get this up and running will review it. HTH!

Thanks for the contribution and sorry for the delay. Could you resolve the conflicts?

@zsxwing Unfortunately, I was not able to solve the failed binary compatibility check.

I am getting

[error]  * method executeVacuum(org.apache.spark.sql.delta.DeltaLog,scala.Option)org.apache.spark.sql.Dataset in class io.delta.tables.DeltaTable does not have a correspondent in current version
[error]    filter with: ProblemFilters.exclude[DirectMissingMethodProblem]("io.delta.tables.DeltaTable.executeVacuum")
java.lang.RuntimeException: delta-core: Binary compatibility check failed!

but am unaware on how to deal with this.

Sorry for the delay. I missed your last comment. You can add an exclusion to https://github.com/delta-io/delta/blob/master/project/MimaExcludes.scala
