Overview
PostgreSQL
PostgreSQL gives you a powerful, open-source object-relational database system with over 35 years of active development. You can manage massive volumes of data while ensuring high levels of resilience and integrity. It supports both SQL for relational queries and JSON for non-relational data, giving you the flexibility to build diverse applications without switching platforms.
You can extend the database with your own data types, custom functions, and code from different programming languages. Whether you are building a simple web app or a complex enterprise system, it provides the tools to maintain data consistency and performance. Because it is open-source, you get a feature-rich environment without licensing fees, supported by a global community of developers.
ScyllaDB
ScyllaDB provides you with a distributed NoSQL database designed for high-throughput and low-latency applications. It uses a shared-nothing architecture that scales linearly with your hardware, allowing you to handle millions of operations per second without the performance bottlenecks found in traditional systems. You can deploy it as a fully managed cloud service or manage it yourself on-premise while maintaining full compatibility with Cassandra and DynamoDB APIs.
You can eliminate the overhead of garbage collection and complex JVM tuning because the system is written in C++. This allows you to achieve predictable performance even under heavy loads, making it ideal for real-time analytics, ad tech, and IoT applications. Whether you are migrating from legacy NoSQL or building a new high-scale service, you get a database that maximizes your infrastructure efficiency and reduces your total cost of ownership.
Overview
PostgreSQL Features
- Complex Query Support Run sophisticated analytical queries using window functions, common table expressions, and advanced indexing to get insights from your data faster.
- Data Integrity Controls Ensure your data remains accurate with robust constraints, including primary keys, foreign keys, unique constraints, and sophisticated exclusion patterns.
- Extensible Architecture Add your own custom data types, operators, and index types to the database to solve unique technical challenges.
- Concurrency Management Allow multiple users to access and modify data simultaneously without locking issues using Multi-Version Concurrency Control (MVCC) technology.
- JSONB Support Store and query unstructured data efficiently with binary JSON support, combining the best of relational and NoSQL worlds.
- High Availability Set up replication and failover clusters to ensure your applications stay online even during hardware failures or maintenance.
ScyllaDB Features
- Shared-Nothing Architecture. Scale your database linearly across multiple nodes and cores to handle massive traffic spikes without losing performance.
- Cassandra & DynamoDB Compatibility. Migrate your existing applications easily using familiar APIs and drivers without rewriting your entire application code.
- Autonomous Operations. Let the database handle complex tasks like compaction, repair, and caching automatically to reduce your manual maintenance effort.
- Workload Prioritization. Run your real-time transactions and analytical queries on the same cluster without them interfering with each other's performance.
- C++ Performance Engine. Eliminate unpredictable latency spikes caused by Java garbage collection for more consistent response times across your application.
- Multi-Cloud Deployment. Deploy your clusters across AWS, GCP, or Azure to ensure high availability and avoid vendor lock-in for your data.
