      Work Description: kanterov edited a comment on issue #7331: [BEAM-6276] 
Fix performance regression.
URL: https://github.com/apache/beam/pull/7331#issuecomment-448941815
 
 
   I asked about how did we find performance regression because as I see from 
the code, there still might be a problem in `FromRowUsingCreator`, where 
`apply` method should use cached lambda, instead of doing reflection for each 
row.
