nosql graph database comparison

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

Krist ófskács, a software architect and consultant who once worked in a number of major companies, blogs on mainstream NoSQL databases (Cassandra, Mongodb, CouchDB, Redis, Riak, Membase, Neo4j, and HBase)) A comprehensive comparison was conducted. Although SQL database is a very useful tool, after 15 years of outstanding performance, the monopoly will be broken.
