Cassandra Quorum Read at Mike Lyles blog

Cassandra Quorum Read. The consistency level of local_quorum. The consistency level quorum means it needs acknowledgment from 51% or a majority of replica nodes across all datacenters. Cassandra uses a blocking read repair to ensure the expectation of monotonic quorum reads i.e. Another common practice is to write at a consistency level of quorum and read at a consistency level of quorum. In quorum consistency a majority of (n/2 +1) nodes of the replicas must respond. That in 2 successive quorum reads, it’s guaranteed the 2nd one won’t get something older than. The consistency level of quorum requires a response from most replicas across a cluster. For example, if you have 7 nodes, with rf = 4, the coordinator will ask for at least 3 nodes to send a successful response to complete the operation (see p.5). Serial operations for these elements can be implemented in cassandra with the paxos consensus protocol, which uses a quorum. Default read and write consistency is one in cassandra. Consistency can be specified for each query. Quorum consistency is consistency in cassandra for high mechanism and to ensure that how many nodes will respond when we will define the read and write consistency in cassandra.
