> Currently, Spark plans are converted to string via StringBuilderWriter when
> memory for strings are allocated sequentially as soon as elements of plans
> are added to the StringBuilder.
> Proposed improvement is StringRope which has 2 methods:
> 1. append(s: String): Unit - adds the string to internal list and increases
> total size
> 2. toString: String - converts the list of strings to strings
