Dawid Wysakowicz commented on FLINK-19440:
------------------------------------------
It's not easy to tell. Increasing the number of records will increase the
throughput, because of the initialization in the first record.
However, from my investigation in the code, the hot path in Avro 1.10 also has
some new code that will result in slower performance (additonal checks and more
complex instantiation logic for SpecificRecords - I checked that under a
profiler).
Therefore as far as I can tell there is a regression on hot path in Avro 1.10.
