cite an extreme example. If we have a Cassandra cluster and it's made up of five physical machines. One of the physical machines is 4 times times the capacity of the other physical machines. Then setting the replication factor to 3 o'clock will cause the same data to be stored on a physical machine with a larger capacity. It's not much better than setting it to 2. So in determining the replication factor of a Cassandra cluster, we carefully set an appropriate value based on the number and

Label:First, why discard access?1. You need to install Access driver on the client's machine PS: This is more annoying, we all know that the simpler the better, install this is too cumbersome for users. 2. Poor performance during Operation PS: People who have used access know that this is a time-consuming query when it comes to large amounts of data. 3. No transaction support Many operations in the actual project need the original transaction support, as for the existence of the business people

Cassandra is that it is not a database, but a distributed network service composed of a bunch of database nodes, and a write operation to Cassandra will be replicated to other nodes, and the Cassandra read operation will also be routed to a node to read. For a Cassandra cluster, extended performance is a relatively simple thing to do, just add nodes to the cluster. 6.Couchbase Couchbase is a JSON-based d
