Summary

To summarize, these are the main points we covered:

  • ScyllaDB splits each table into tablets and balances them across the nodes of the cluster
  • It’s a distributed, highly available, high performance, low maintenance, highly scalable NoSQL database
  • In ScyllaDB all nodes are created equal, there are no master/slave nodes
  • Data is automatically distributed and replicated on the cluster according to the replication strategy
  • ScyllaDB supports multiple data centers
  • ScyllaDB transparently partitions data by using the hash values of keys

1. What does ScyllaDB do with a row's partition key?
2. How do newer versions of ScyllaDB distribute a table's data across the cluster?
3. A keyspace uses NetworkTopologyStrategy with {'DC1': 3, 'DC2': 2}. How many copies of each row does the cluster store?
4. Which replication strategy should you use in production, and is the only one that tablets support?
