A strategy that determines how a hive metastore schema is evolved for a given target schema.
For example, a strategy may choose to alter the hive table to add any missing columns. Or it may choose to abort a write by throwing an exception. Or it may choose to leave the schema as is and drop the columns from the input rows.
