Ernesto Ocampo created ARROW-2392: ------------------------------------- Summary: pyarrow RecordBatchStreamWriter allows writing batches with different schemas Key: ARROW-2392 URL: https://issues.apache.org/jira/browse/ARROW-2392 Project: Apache Arrow Issue Type: Bug Reporter: Ernesto Ocampo
A RecordBatchStreamWriter initialised with a given schema will still allow writing RecordBatches that have different schemas. Example: {code:java} schema = pa.schema([pa.field('some_field', pa.int64())]) stream = pa.BufferOutputStream() writer = pa.RecordBatchStreamWriter(stream, schema) data = [pa.array([1.234])] batch = pa.RecordBatch.from_arrays(data, ['some_field']) # batch does not conform to schema assert batch.schema != schema writer.write_batch(batch) # no exception raised writer.close() {code} -- This message was sent by Atlassian JIRA (v7.6.3#76005)
