Jira issue originally created by user @beberlei:

There are currently some drawbacks with identifier hashing:

  • They only work on one level for derived keys
  • The code is suspect to high performance requirements
  • Composite Keys might be suspect to weird bugs if they contain spaces.

There is a PR by goetas (#232) that solves some issues, however adds a performance hit.

We should move the conditional logic of this code out and use a strategy pattern to improve both performance and robustness of this code.
