Examples of RangeBasedPartitionProperties

com.linkedin.d2.balancer.properties.RangeBasedPartitionProperties
Assumption: every partition has equal size. keyRangeStart is the start point of the keys used by the service; typically it is 0 the formula to calculate the partitionId for a key is: (key - keyRangeStart)/partitionSize;
