Description

On a selectKey the old code looks up the index of the new key field in the value schema per-row processed. This index is constant and can be pre-calculated just the once.

Testing done

mvn test

Reviewer checklist

  • Ensure docs are updated if necessary. (eg. if a user visible feature is being added or changed).
  • Ensure relevant issues are linked (description should include text like "Fixes #")
