> When exporting data as a table the user can choose to split data in buckets by choosing the columns and the number of buckets. Currently there is a hard-coded limit of 99'999 buckets.
> However, for heavy workloads this limit might be too restrictive, a situation that will eventually become more common as workloads grow.
> As per the comments in SPARK-19618 this limit could be made configurable.
