 It uses Invertible Bloom Lookup Table (IBLT), also known as Invertible Bloom Filter (IBF), to represent
 the state of a producer in partial sync mode and the state of a node in full sync mode. An IBF is a

 In partial sync, PSync uses a Bloom Filter to represent the subscription of list of the consumer.
