Strong-consistency namespace compatibility during Aerospike 6.x to 7.x rolling upgrade The goal is to keep a strong-consistency namespace available and linearly consistent while upgrading nodes one at a time from Aerospike 6.x to 7.x. Strong consistency guarantees linearizable single-record writes, but Aerospike has no multi-record transaction rollback, so c
Goal: Detect meaningful Aerospike latency or resource issues while minimizing unnecessary notifications. Constraint: Native threshold alerts fire on instantaneous samples and lack time‑of‑day or maintenance‑window suppression, causing flapping; using Prometheus with recording rules adds exporter overhead but enables sliding‑window averaging and hysteresis fo
Goal is a repeatable local development environment for Aerospike Server where namespace configuration and storage engine behavior are predictable across restarts and resource constrained runs. Constraints include small memory or disk limits to surface resource pressure, choice between in-memory and persistent storage per namespace, and single-node cluster de
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
I am planning a new Aerospike Community Edition deployment and need to know whether the default configuration exposes the service port to unauthenticated clients on every network interface. The documentation notes that default bind addresses and authentication requirements can differ between Community and Enterprise editions and across server versions, but i
Goal The cluster should continue to accept writes even when a node goes down, maintaining the configured replication‑factor. Constraints & Uncertainty Replication‑factor is set to 3 but the cluster only has 2 active nodes. The write operation blocks and errors appear in the logs. It is unclear whether the failure is due to the replication‑factor exceedin
Goal Diagnose deployment failures that surface in the Aerospike logs as xdcr: replica write failed entries, focusing on the impact of the use-async-write setting introduced in Aerospike 7.3. Constraints Logs provide timestamps for primary acknowledgments and for the completion of asynchronous replica writes but do not directly expose ordering guarantees or c
Aerospike deployments often require strict isolation to prevent unauthorized public access. While the network.interface-address configuration allows binding services to specific internal IP addresses, the default behavior of binding to 0.0.0.0 can expose the database to the public internet if external firewalls are misconfigured or absent. When implementing
Namespace Durability in Strong Consistency Mode Aerospike Strong Consistency (SC) mode utilizes a consensus protocol to ensure linearizability. When the commit-to-device configuration is set to true , the system is intended to force an fsync() to the storage device before acknowledging a write to the client, ensuring that acknowledged data survives an unclea
