If your product catalog needs to be available both online (cloud) and offline (mobile), note that the NoSQL favorite Couchbase was updated to version 7.6.6 in 2025.
This release unites AI-driven vector search abilities and full mobile data sync under one roof.
Imagine a store POS losing its internet connection yet still recording loyalty points—and then syncing to the cloud within seconds once back online.
For retail and mobile apps, that kind of flexibility is synonymous with preserving customer loyalty.
Warning: Vector search and active-active mobile synchronization in Couchbase 7.6 deliver value only with proper resourcing and nonstop monitoring; a poorly managed cluster shatters customer trust, not just your data.
2025 Feature Highlights
Cosine Similarity Support – Ask “Find me tracks similar to this melody,” and the system looks for semantic similarity, not just keyword matches.
Active-Active Mobile Sync – Even if HQ loses connectivity, store tablets keep writing data; once the link is back, changes merge without conflict.
Hardware Upgrade Alert – CPUs without AVX2 (pre-2013) are no longer supported—plan upgrades accordingly.
Tips for Easy Operations
Isolate Vector-Search Nodes – Heavy search workloads shouldn’t drag down write performance.
Keep the Backup Tool Current – Restores may fail if you don’t use cbbackupmgr 7.6.
Prometheus Labeling – Enable the new clusterLabels option to avoid mixing multiple clusters on the same dashboard.
Cloud & Edge Scenarios
Capella DBaaS – Vector search is in beta; expect extra charges per GB.
AWS Graviton3 – AVX2-enabled and cost-efficient.
Mobile Edge – With Couchbase Lite 3.x, offline AI (RAG) scenarios are possible, syncing when connectivity returns.
