I have a problem in converting between InternalRow and String, as now we
are using InternalRow to represent ColumnStat.
Since we want to persist ColumnStat into metastore and we use table
parameters (a string to string map) to carry the stats, we need to encode
ColumnStat to String when storing and decode ColumnStat from String when
loading.
Are there any APIs I can utilize? Or do I have to write something like a
serializer?
Any advices?
