What Is GeminiDB DynamoDB-Compatible API?
Copied.
What Is GeminiDB DynamoDB-Compatible API?
GeminiDB is completely compatible with Amazon DynamoDB, so you can access GeminiDB DynamoDB-Compatible API through SDKs or CLIs and smoothly migrate data from DynamoDB to GeminiDB without refactoring. GeminiDB DynamoDB-Compatible API is secure and reliable. It removes constraints of closed-source software.
- Secure and reliable
- VPCs, subnets, security groups, SSL, and fine-grained permissions control ensure database security and user privacy.
- Cross-region active-active DR is supported. You can deploy an instance across three AZs and quickly back up or restore data.
- The distributed architecture ensures fault tolerance for N-1 nodes.
- No pain points of open-source software
- Storage can be scaled in seconds without affecting services.
- Compute nodes can be added in minutes. A jitter may last only a few seconds.
Architecture
GeminiDB DynamoDB-Compatible API is embedded in kernel services of GeminiDB Cassandra API and communicates with DynamoDB over HTTPS. In addition, GeminiDB DynamoDB-Compatible API supports CQL. The following figure shows the overall architecture.
Figure 1 GeminiDB DynamoDB-Compatible API architecture
GeminiDB strictly follows the DynamoDB syntax and data models, so DynamoDB applications can be easily migrated to GeminiDB DynamoDB-Compatible instances. In addition, GeminiDB DynamoDB-Compatible API provides automated management and O&M functions, such as automatic backup, fault detection, and fault tolerance.
Highlights
- Low costs
Companies generate increasing amounts of data as their businesses grow. Handling frequent read and write requests on DynamoDB becomes costly. GeminiDB DynamoDB-Compatible API provides higher throughput at half the cost of DynamoDB, especially when there is a large amount of data.
- Flexible deployment
DynamoDB is a fully managed service that needs to follow certain rigid deployment requirements. In contrast, GeminiDB DynamoDB-Compatible API offers flexible deployment options. It can run on both private and public clouds, avoiding platform lock-in. GeminiDB DynamoDB-Compatible API also delivers stable and efficient performance in all deployments.
- Smooth migration
GeminiDB DynamoDB-Compatible API is fully compatible with DynamoDB syntax and data models, so you can migrate data from DynamoDB to GeminiDB DynamoDB-Compatible API without making changes to applications. This makes the migration simpler, faster, and less disruptive to your operations.
