DB Plus for Efficient Data Transfer

GeminiDB's DB Plus facilitates data transfer with relational databases and big data services. It eliminates data silos and unleashes data value.

1. DB Cache of GeminiDB Redis API automatically accelerates relational database data transfer, supports higher concurrency and lower latency, and simplifies the application architecture.

2. DB Load of GeminiDB Redis API enables massive volumes of user feature data to be imported five times faster. It ensures more precise RTA-based ad placement and accurate recommendations.

3. DB Insight of GeminiDB Influx API supports real-time import and queries of IoV time series data. Billions of metrics from millions of vehicles can be written and analyzed in real time.

4. DB Detect of GeminiDB Influx API provides built-in metrics for users to create a custom streaming anomaly detection task. It combines various components to simplify the application architecture.

5. DB Lake of GeminiDB Influx API automatically converts time series data into a Parquet file and imports the data to the lake at a T+1 delay. It integrates online and offline data streams of traditional IoV, simplifying the application architecture.

6. DB Log of GeminiDB Cassandra API automates data archiving and offloads relational databases online.

7. DB Search of GeminiDB Cassandra API is an integrated simplified search service that is compatible with SQL queries.

DB Plus is now available for general use in CN North-Beijing4, CN East-Shanghai1, and CN South-Guangzhou. You can buy specified APIs on the GeminiDB console.

GeminiDB Redis supports Redis Cluster architecture.

• Both proxy cluster and Redis Cluster instances support horizontal and vertical scaling and can handle millions of QPS and tens of terabytes of data. Redis Cluster is recommended because it features low latency, high concurrency, and high scalability.
• All instances in a proxy cluster or Redis Cluster can be read and written, improving resource utilization. Shared storage provides high availability. In the primary/standby architecture, only a primary instance can be read and written. Therefore, the cluster architecture is recommended.
