Kudu is designed based on the HBase structure and can implement fast random read/write and update functions that HBase is good at. Kudu and HBase are similar in architecture. The differences are as follows:
- HBase uses ZooKeeper to ensure data consistency, whereas Kudu uses the Raft consensus algorithm to ensure consistency.
- HBase uses HDFS for resilient data storage, whereas Kudu uses TServer to ensure strong data consistency and reliability.
