Architecture & Use Cases6 stats

Aerospike supports multi-record transactions across bins within a single record and supports ACID-like operations depending on configuration, per Aerospike transaction documentation

Redis can persist in-memory data using RDB snapshots and AOF logs, per Redis persistence documentation (RDB and AOF are core in-memory store durability features)

IBM Db2 with BLU Acceleration uses columnar in-memory processing options for analytics, per IBM Db2 documentation

SAP HANA smart data access supports query federation and in-memory processing over remote data sources, per SAP HANA documentation

Apache Ignite supports persistent memory (persistence) with write-ahead log options; Ignite documentation describes WAL (Write-Ahead Logging) enabling durability beyond pure RAM use

Redis Streams provide event log semantics and consumer groups; documentation specifies Redis Streams as a data structure for stream processing with consumer groups

Interpretation

Architecture & Use Cases Interpretation

Across the architecture and use cases examples, most in-memory data stores emphasize production-grade persistence and interoperability, with Redis explicitly supporting both RDB snapshots and AOF logs plus stream-style event processing, while systems like Aerospike and Ignite highlight transactional and WAL-backed designs that go beyond simple caching.

Google Cloud Memorystore for Redis offers instance sizing options from 1.2 GB to 240 GB per node (cost drivers for in-memory Redis deployments), per product pricing documentation

AWS ElastiCache supports 'Redis Cluster mode' and multi-AZ replication, increasing cost via replication factor; replication is explicitly documented as primary + replicas (1+ replica nodes)

IBM Power systems and Db2 licensing: Db2 on Power can use 'Memory on Demand' (MoD) to scale memory utilization (cost economics), per IBM Power documentation
