Major Description
I hope kudu can support snapshot management like iceberg, can create, query, expiration snapshots, support query data changes between two snapshots. This is very necessary, when we write data to kudu in real time, often expect the data to be like the past, query the data before a fixed time, or query the changes between two snapshots in order to facilitate real-time calculation or incremental calculation, in the case of data lake is becoming more and more of a trend, Real-time computation/incremental computation and snapshot management are very much needed new features of kudu.
