Test Result

Over 1 TB of data was injected for pressure testing. The test results are as follows:

• Data compression ratio

  1.1 TB of data (about 3.8 billion data records) is written and the occupied space is 155 GB after compression. The data compression ratio is about 13.8%.

• Performance

  The total QPS reaches 1.6 million, the total read request traffic is 1.5 Gbit/s, and the CPU usage ranges from 60% to 70%.

  The average latency is about 0.7 ms, the p99 latency is about 1.77 ms, and the long-tail latency of p99.99 is about 8.03 ms.

The results show that GeminiDB Redis API has stable latency in large-scale RTA scenarios. With data compression and decoupled compute and storage architecture, GeminiDB Redis API is an ideal KV database for advertising services.
