Hi @Alejandro Martinez​ :

 I don't think we have any such command to get the statistics before vacuum and after vacuum.

 Atleast I haven't come across any.

 If you want to capture more details, may be you can write a function to capture the statistics as below.

 Data files size:

 Data files count:

 Before:

var getDataFileSize = 0

val getDataFileCount = dbutils.fs.ls(<Your Table Path>").toList.size

dbutils.fs.ls(<Your Table Path>)

 .foreach

 {

  file =>

  getDataFileSize = getDataFileSize + file.size

 }

 After:

   Repeat above

Lets see if other community members have better ideas on this.
