for our graphical database? In fact, this is not difficult, you just need to understand the design of the graph database to use a series of points.The first is to distinguish between node sets, nodes, and relationships in the graph. In the past design of relational database, we often use a table to abstract a class of things. As with the concept of human beings,
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
tables in the relational database are all stored in a formatted data structure. The composition of each tuple field is the same, even if not all of the fields are required for each tuple, but the database assigns all the fields to each tuple, which makes it easy to link between the banner tables, but from another point of view it is also a factor in relational database
