WHAT FIVE P99 CONF TALKS REVEAL ABOUT DATABASE TRADE-OFFS

Summary from the TLDR Data newsletter

A sponsored P99 CONF round-up exposes the costs behind several database designs: object storage trades low-cost durability for cold-read latency, read-optimized engines trade RAM and write amplification for tail latency, and vector search trades quantization and cache complexity for scale. The reported benchmarks are workload-specific, but the recurring lesson is: removing one bottleneck moves the constraint elsewhere.
