      Description

      We need to decide on some format for reading/writing data with schema from/to table core datasets.

      Specifically, we need to decide how to store records. A reasonable way may be to decompose a record into its fields, and store each field as a separate column. This can be done recursively for nested records.

      For 2.7, it may be that the case that we only support simple types (int, long, float, double, byte[], map, array) as a first cut, but we should at least make a conscious decision on what to support.
