Understand how replication impacts read and write performance.
- [Instructor] Now let's step into a little more detail…with regards to replication.…Cassandra provides for high availability and…query performance by keeping multiple copies of data.…Cassandra clusters are organized into a logical ring,…such as shown here.…When we create a keyspace on a cluster,…we specify the number of replicas we'd like to keep…and the strategy we'd like to use to determine where…to store the replicas.…The number of replicas we store…is called the replication factor.…A replication factor of one means only one copy…of data is kept.…
A replication factor of two keeps two copies.…While a replication factor of three keeps three copies…and so on.…When working with a local setup for development,…using a replication factor of one is reasonable.…Production environments typically use a replication factor…of two or more.…Cassandra has two strategies for placing replicas…in a cluster, the simple strategy…and the network topology strategy.…As you probably inferred,…the simple strategy is the less complicated strategy.…
