cassandraImplementing Strong Consistency in Aerospike for Linearizable Data
Learn how to configure Aerospike Strong Consistency to eliminate stale reads. This guide covers quorum-based writes, configuration steps, and the performance trade-offs of linearizable data.
aerospikeSecondary index scan limitations under strong consistency quorum
Aerospike provides strong consistency for key‑value operations through namespace‑level read and write quorum settings. When these are set to all or majority , the system ensures linearizable reads for direct key accesses by coordinating across replicas. However, secondary index scans do not appear to honor these same namespace‑level quorum configurations. Ev
Cassandra Read Consistency ONE vs QUORUM for RF 3
Goal: select a read consistency level for a three-node Cassandra 4.x cluster with replication factor 3 that serves user-profile reads. The application must avoid stale reads, but the p99 latency budget is tight. Local single-node testing with consistency ONE hides replication lag because the only replica satisfies the read requirement. In production, ONE can
