Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

CouchDB

Append-only storage model may have performance implications for certain workloads with high update rates
Requires network synchronisation for cluster data consistency; can introduce latency in multi-master scenarios
No explicit support for complex joins; MapReduce queries may be inefficient compared to relational databases

Deno

Egress bandwidth overage costs $0.20/GB which can become expensive for high-traffic applications
CPU time overage is $0.10/hour on Pro and Builder tiers, adding to costs for compute-intensive workloads
Enterprise pricing is not disclosed; requires sales contact
