Work Description: KyleSchoonover opened a new pull request #1604:
URL: https://github.com/apache/avro/pull/1604
The original intent of this improvement was to increase the performance of
the Generic / Specific Reader classes in regards to RecordSchema. I tested for
both netcore 3.1 and .Net 6.0. The performance increase is around 15% of
netcore 3.1. For .Net 6.0 it is around 7%.
In addition, I tested with a hashset assuming multiple repeating records
within a large schema, but it actually decreased performance.

> GenericReader/SpecificReader spend a lot of time comparing the reader/writer

> DatumReader implementation.
