advantages are: fast and accurate, the disadvantage is: cost storage space. To improve efficiency we can use the hash table and map the elements in the collection to a bit in the bitmap, which saves space and time to find. But because of the hash conflict, we may have a miscarriage of judgment, that is, different elements may produce the same address after the hash function. What are the applications of the Bron filter?1. Google's well-known distributed database BigTable uses a

bringing up a kafka-based ordering Service The sorting service needs to handle all transaction messages in the FABIRC network, which is the key to the whole network. Fabric currently (2018/01) supports two types of sorting: Solo and Kafka. In the generation environment, the Orderer node needs to be sorted by the Kafka cluster to improve its reliability. This article describes how to configure the sorting node based on Kafka. The topology of the netwo
