Apache Cassandra Suppresses Bandwidth Overruns

Question

during testing Apache Cassandra, I inserted 1000 rows of data. I allow him to spread to another machine on the local network. This is a 2-machine cluster. I control the network connection between the two machines. The total data that I expected to flow between the two servers should be around 25 MB, including all column names, column values, and timestamps). But the actual data sent and received between them was a whopping 362 MB! Does anyone know why there is such an overhead? Thanks you

Answer 1

It is interesting. It is probably easier to understand what happens if you look at one operation at a time.
