<p>The resulting distribution of partitions of a single topic has the following contract:

<li>1. Uniformly distributed across subtasks</li>
<li>2. Partitions are round-robin distributed (strictly clockwise w.r.t. ascending
subtask indices) by using the partition id as the offset from a starting index

determined using the topic name).</li>

contract to locally filter out partitions that it should not subscribe to, guaranteeing

uniformly distributed manner.

Determines the start index of the substring in the String most recently added to the MDAG
that corresponds to the _transition path that will be next up for minimization processing.
<p/>
The "minimization processing start index" is defined as the index in {@code prevStr} which starts the substring
corresponding to the _transition path that doesn't have its right language extended by {@code currStr}. The _transition path of
the substring before this point is not considered for minimization in order to limit the amount of times the
equivalence classes of its nodes will need to be reassigned during the processing of Strings which share prefixes.
@param prevStr the String most recently added to the MDAG
@param currStr the String next to be added to the MDAG
@return an int of the index in {@code prevStr} that starts the substring corresponding
to the _transition path next up for minimization processing | [
