Stargate
An open-source data API gateway that sits between applications and Cassandra, enabling multiple APIs and data models.
What is Stargate?
Stargate is an open-source data API gateway that sits between client applications and a Cassandra database. It enables developers to use Cassandra for any workload by supporting multiple APIs like REST, GraphQL, and Document APIs, along with pluggable data types and access methods. It solves the problem of database and API fragmentation by providing a unified, extensible framework for data access.
Developers and operators working with Cassandra who need flexible API access, microservice scalability, or want to expose Cassandra data through modern interfaces like GraphQL or REST. It's also for teams seeking to avoid vendor lock-in with proprietary database gateways.
Developers choose Stargate because it offers a highly extensible, open-source gateway that supports multiple APIs and data models out of the box, eliminating the need to switch databases or learn new APIs for different workloads. Its microservice architecture allows independent scaling of components, providing operational flexibility and performance.
Overview
An open source data gateway
Use Cases
Best For
- Exposing Cassandra data through REST or GraphQL APIs
- Building microservices that need independent scaling of database access layers
- Adding document-based data models on top of Cassandra
- Implementing pluggable authentication and authorization for database access
- Deploying a high-performance data gateway with gRPC and CQL support
- Creating a unified data access layer for multiple application workloads
Not Ideal For
- Projects using databases other than Apache Cassandra or DataStax Enterprise
- Simple applications that only need direct CQL access without API abstraction
- Teams with limited DevOps resources for managing microservice deployments
- Use cases requiring real-time data streaming or event processing not supported by Stargate's APIs
Pros & Cons
Pros
Exposes Cassandra data through REST, GraphQL, and Document APIs via independently scalable microservices, enabling diverse application workloads without database switching.
Supports Cassandra 3.11, 4.0, and DataStax Enterprise 6.8 through interchangeable persistence services, allowing flexibility in storage layer upgrades and compatibility.
Enables independent deployment and scaling of coordinator nodes, API services, and storage nodes, optimizing resource usage as described in the architecture.
Offers pluggable auth with table-based storage and JWT support, allowing customization of security layers without modifying core components.
Cons
Currently specific to Cassandra-compatible backends, restricting use with other databases and creating storage vendor lock-in, as admitted in the README.
Requires Docker or Kubernetes for setup, and the microservice architecture adds operational overhead compared to simpler monolithic solutions.
Maintains a fast release cycle with major versions every 6-12 months, leading to potential breaking changes and frequent update needs, as outlined in the versioning strategy.
