When Should You Stick with PostgreSQL?
Alternatives are not always the right move. PostgreSQL remains strong in these scenarios.
- +Extensible architecture supports GIS, time-series, and vector data
- +ACID compliance and MVCC ensure high data integrity and concurrency
- +Advanced indexing (GIN, GiST, BRIN) accelerates complex queries
- +Rich data types including native JSONB, arrays, and range types
- +Mature, battle-tested reliability for mission-critical applications
- -Requires manual tuning for high-throughput, write-heavy workloads
- -Connection management can be resource-intensive at massive scale
- -No built-in horizontal scaling; requires third-party solutions
- -Vacuuming process can cause performance overhead on busy tables

Expert Take
PostgreSQL works well when building relational applications that require strict SQL compliance and advanced indexing. The friction starts when deploying it on its default configuration, which is poorly optimized for high-performance workloads and requires manual tuning for write-heavy operations. Before buying, compare vs MySQL, which is also free but lacks PostgreSQL's advanced object-relational features and has more architectural limitations.
Oleh KemFounder & Lead AnalystOpen-source distributed SQL database with MySQL compatibility for HTAP workloads.. Rated 4.7/5 vs 4.5/5 for PostgreSQL.
- +HTAP eliminates separate analytics warehouse for many use cases
- +MySQL compatibility reduces migration complexity
- +Strong horizontal scaling for high-write workloads
- +Free serverless tier for development
- +HTAP (Hybrid Transactional/Analytical)
- +MySQL Wire Protocol
- +Horizontal Scaling
- +TiFlash (Columnar Engine)
- −It is very unusual and jarring that the IDs in different tables jump and do not start from zero.
- −TiDB Cloud can be improved, particularly because the interface is very old.
In-memory data structure store for caching, pub/sub, and latency-sensitive workloads..
- +Sub-millisecond latency: fastest data store for caching
- +Universal: supported by every framework and language
- +Rich data structures for real-time use cases
- +Redis Stack adds search, JSON, and vector capabilities
- −There are some points where I feel Redis can be improved.
- −There are a few areas where Redis could improve.
- −Redis could improve its efficiency in handling locally stored data, not just Amazon Cloud or Google Cloud.
A cloud data platform that unifies warehousing, data lakes, and AI/ML workloads with decoupled storage and compute.. Rated 4.7/5 vs 4.5/5 for PostgreSQL.
- +Decoupled storage/compute allows independent, instant scaling
- +Zero-copy cloning creates instant, writable copies for dev/test
- +Secure Data Sharing enables live data access without ETL
- +Snowpark offers native Python/Java/Scala processing in-database
- +Consistent experience and replication across AWS, Azure, and GCP
- +Separation of Storage and Compute
- +Multi-Cluster Warehouses
- −Credit-based pricing can be complex and lead to unpredictable costs
- −Lacks fine-grained indexing control, impacting some query tuning
- −No support for on-premise or hybrid deployments; cloud-only
Unified data and AI platform combining Delta Lake, SQL analytics, and ML training on a single platform.. Rated 4.7/5 vs 4.5/5 for PostgreSQL.
- +Lakehouse architecture eliminates ETL between data lake and warehouse
- +MLflow is the de-facto ML experiment tracking standard
- +Unity Catalog provides unified governance across data and AI
- +Delta Lake open format avoids vendor lock-in
- +Delta Lake (Open Table Format)
- +Apache Spark
- +MLflow (ML Tracking)
- −As a data engineer, I see cluster failure in our Databricks user databases as a major issue.
- −I heard that a new feature is being developed for SAP that can bring SAP data directly into the platform for generating reports.
- −The API deployment and model deployment are not easy on the Databricks side.
Distributed search and analytics engine built on Apache Lucene for full-text search and log analytics at scale..

- +Full-featured, production-ready open-source core; no vendor lock-in
- +Column-oriented storage
- +Vectorized query execution
- −No multi-row transactions (ACID); not suitable for OLTP workloads
- −Point updates and deletes are expensive, batch-oriented operations
- −Limited full-text search capabilities compared to dedicated search engines
The most widely deployed open-source relational database, powering WordPress, Drupal, and most PHP apps..
- +Most widely deployed database: abundant expertise and tooling
- +Battle-tested for 30 years on the web
- +HeatWave adds analytics and ML without ETL
- +Available managed on AWS RDS, Azure, GCP
- +ACID Transactions (InnoDB)
- −The data masking functionality should be improved as well as the native encryption functionality in the MySQL database.
- −The performance issues in the product can be considered as an area where improvements are required.
- −In MySQL, we need to define every table beforehand.
A distributed SQL database that provides next-level consistency, ultra-resilience, and geo-partitioning for global apps..
- +Survives disk, machine, rack, and datacenter failures with zero data loss.
- +Horizontally scales both reads and writes by simply adding new nodes.
- +PostgreSQL wire-protocol compatibility simplifies migration and tooling.
- +Geo-partitions data to keep it close to users, reducing latency.
- +Offers strongly consistent, ACID-compliant transactions across regions.
- +Distributed SQL
- +PostgreSQL Wire Protocol
- +Multi-Region Replication
- −Higher write latency than single-region databases due to consensus protocol.
- −Not a drop-in PostgreSQL replacement; lacks stored procedures and triggers.
- −Complex distributed architecture can have a steeper learning curve.
