Storage Engine Selectorv1.0.0

An ad-tech company experiencing write amplification and compaction pauses in their PostgreSQL-based ad impression logging system needs to evaluate LSM-tree alternatives like RocksDB or Cassandra to handle high write throughput and reduce latency spikes.

A smart factory ingests millions of sensor readings per second. Storage engineers consider LSM-tree for write optimization and size-tiered compaction to avoid compaction stalls, while still supporting occasional range queries for historical analysis.

A SaaS startup building a real-time analytics dashboard for e-commerce clients needs to decide between an in-memory store (Redis) for low-latency aggregations and an LSM-tree store (RocksDB) for durability and crash recovery.

A fintech company requires strict ACID transactions and predictable read latency for a payment processing system. They use the skill to justify sticking with B-tree (PostgreSQL/InnoDB) over LSM-tree, given the need for strong consistency and range scans.

A social media platform facing latency spikes during compaction in their Cassandra cluster uses the skill to evaluate switching to leveled compaction or tuning bloom filters, balancing write throughput with read performance for user feeds.

Offer database storage recommendations as a premium add-on in a cloud infrastructure SaaS, where customers pay for personalized engine selection and tuning guidance based on their workload.

Provide expert consulting to companies migrating between storage engines, using the skill's scored comparison to justify migrations and reduce risk, charging per engagement.

Integrate the skill into CI/CD pipelines as an automated architecture advisor, charging per analysis run or as part of a larger DevOps platform subscription.
