| # Performance |
| |
| This chapter introduces the performance characteristics of IoTDB from the perspectives of database connection, database read and write performance, and storage performance. |
| The test tool uses IoTDBBenchmark, an open source time series database benchmark tool. |
| |
| ## Database connection |
| |
| - Support high concurrent connections, a single server can support tens of thousands of concurrent connections per second. |
| |
| |
| ## Read and write performance |
| |
| - It has the characteristics of high write throughput, a single core can handle more than tens of thousands of write requests per second, and the write performance of a single server can reach tens of millions of points per second; the cluster can be linearly scaled, and the write performance of the cluster can reach hundreds of millions points/second. |
| - It has the characteristics of high query throughput and low query latency, a single server supports tens of millions of points/second query throughput, and can aggregate tens of billions of data points in milliseconds. |
| - |
| ## Storage performance |
| |
| - Supports the storage of massive data, with the storage and processing capabilities of PB-level data. |
| - Support high compression ratio, lossless compression can reach 20 times compression ratio, lossy compression can reach 100 times compression ratio. |
