Work Description: kanterov commented on issue #7331: [BEAM-6276] Fix
performance regression.
URL: https://github.com/apache/beam/pull/7331#issuecomment-449444610
> @kanterov where do you see apply() doing reflection per row?
@reuvenlax I did a rough benchmark (to be verified and investigated) of
using `JavaBeanSchema` vs. hand-crafted code:
```
Benchmark Mode Cnt Score Error Units
FromRowBenchmark.javaBeanSchema thrpt 6 0.007 ± 0.001 ops/ns
FromRowBenchmark.javaCode thrpt 6 0.071 ± 0.017 ops/ns
```
I would investigate and get back to you.
