public class MerkleTreeConfig extends Object implements IdentifiedDataSerializable
A larger depth means that a data synchronization mechanism will be able to pinpoint a smaller subset of the data structure contents in which a change occurred. This causes the synchronization mechanism to be more efficient. On the other hand, a larger tree depth means the merkle tree will consume more memory.
A smaller depth means the data synchronization mechanism will have to transfer larger chunks of the data structure in which a possible change happened. On the other hand, a shallower tree consumes less memory. The depth must be between and (exclusive). The default depth is .
As the comparison mechanism is iterative, a larger depth will also prolong the duration of the comparison mechanism. Care must be taken to not have large tree depths if the latency of the comparison operation is high. The default depth is .
