Where each one falls short
Documented limitations, not opinions. Every one is a constraint you would hit in normal use.
Couchbase
- The free tier is a single node with 8 GB of storage and forum support only
- Node rates are hourly and quoted as starting figures, from $0.15 an hour on Basic to $0.49 on Enterprise
- The Developer Pro and Enterprise plans require 3 nodes, so the hourly rate multiplies before any usage
- Backup storage is billed separately at $0.07 per GB a month, and analytics backups at $0.14
- Support response time is a plan feature, at 8 hours on Developer Pro against 30 minutes on Enterprise
- AI and analytics run as separately priced planes at up to $0.86 an hour per node
YugabyteDB
- Missing PostgreSQL functions and extensions despite claiming compatibility
- Not a true PostgreSQL replacement requiring schema and query compatibility testing before migration
- Requires careful isolation level management or risk data corruption in production
- Lacks built-in OLAP capabilities, requiring external systems for analytics
- Coupled compute and storage scaling reduces optimization flexibility

Answered from the vendors’ own pages
YugabyteDB: Is YugabyteDB a true drop-in replacement for PostgreSQL?
No, YugabyteDB is PostgreSQL-compatible but not a zero-change drop-in replacement. It requires compatibility testing with queries, stored procedures, and ORM configurations before migration.
SourceYugabyteDB: What isolation levels does YugabyteDB support?
YugabyteDB allows per-query selection between serializable isolation for critical operations and read-committed for analytics. However, this flexibility requires careful management to avoid accidental data corruption.
SourceYugabyteDB: Does YugabyteDB support both SQL and NoSQL workloads?
Yes, YugabyteDB offers YSQL for PostgreSQL-compatible SQL and YCQL for Cassandra-like NoSQL workloads, using the same DocDB storage engine to support both simultaneously.
SourceYugabyteDB: Can YugabyteDB scale compute and storage independently?
No, YugabyteDB couples compute and storage scaling, unlike TiDB which separates them. This means scaling decisions are less flexible and optimization is more complex.
