Min Shen commented on SPARK-11597:
----------------------------------
Is there any further update on this ticket?
We have recently seen a scenario where we are using spark-avro to read avro
files containing only a single record with an array field containing 135K
elements.
While it only took 1-2 seconds for Avro to read the file and to convert the
GenericRecord into Row, it took RowEncoder ~10min to convert the Row object
into InternalRow.
[~cloud_fan], do you think the patch you created will help improving the
situation here?
