Slides: https://www.slideshare.net/DataStax/r... | Many users set the replication strategy on their keyspaces to NetworkTopologyStrategy and move on with modeling their data or developing the next big application. But what does that replication strategy really mean? Let's explore replication and consistency in Cassandra.
How are replicas chosen?
Where does node topology (location in a cluster) come into play?
What can I expect when nodes are down I'm querying with a Consistency Level of local quorum?
If a rack goes down can I still respond to quorum queries?
These questions may be simple to test, but have nuances that should be understood. This talk will dive into these topics in a visual and technical manner. Seasoned Cassandra veterans and new users alike stand to gain knowledge about these critical Cassandra components.
