> DatumReader.match_schemas(writers_schema, readers_schema) is called on every single read from the DatumReader.  However, for almost every read, the schemas used are the object members self.writers_schema and self.readers_schema.  match_schemas should be checked only once in this case, and only when the object members are modified.  This takes up 20% of my parse time upon profiling.
