The short version
- Each has a real cost: CouchDB append-only storage model may have performance implications for certain workloads with high update rates; RudderStack on the free plan data processing stops after a second consecutive overage rather than being billed, so exceeding 250,000 events twice breaks the pipeline
- They diverge on capability: CouchDB covers Multi-master Replication, RudderStack covers Data collection.

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
RudderStack
- On the free plan data processing stops after a second consecutive overage rather than being billed, so exceeding 250,000 events twice breaks the pipeline
- The free plan allows 250,000 events a month
- Growth starts at $265 a month for 1 million events, with volume sold in tiers up to 25 million
- Overage is charged as the gap to the next tier's price rather than per event, so a small excess costs a full tier step
