----------------------------------
Summary: Python Avro match_schemas called redundantly
Key: AVRO-1304
URL: https://issues.apache.org/jira/browse/AVRO-1304
Project: Avro
Issue Type: Bug
Components: python
Affects Versions: 1.7.4
Reporter: Uri Laserson
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.
