[GitHub] jena issue #306: Algorithms for JENA-1414

Github user afs commented on the issue:

    https://github.com/apache/jena/pull/306
  
    Revised version.
    
    The co-iteration algorithm (choice 3) is complicated. Determining the right thing to do each time is expensive and still a pragmatic choice with graph probing. The app may well know what to do so call the appropriate method as already documented.
    
    My suggestion is algorithm 2 (a slightly improved version of the patch on  JENA-1414), document what to do if src is a large persistent database and remove the complicate algorithm 3.
    
    If that is our decision, I will produce a much simpler commit for algorithm 2.
