## Hardware Configuration Recommendations

* Primarily for initial configuration suggestions. During the testing phase, adjustments should be made based on the specific performance of the testing environment.

### Recommended Based on Data Volume

* Enable acceleration engine for all data
* Perform analysis on a single table only

| Data Volume (Unit: Rows) | CPU      | Memory       | Available Disk Space |
|--------------------------|----------|--------------|-----------------------|
| 0 ~ 10 million           | 8 threads | 16G ~ 24G    | 100G                 |
| 10 million ~ 50 million  | 16 threads | 24G ~ 32G   | 500G                 |
| 50 million ~ 100 million | 16 threads | 32G ~ 64G   | 500G ~ 1T            |

### Recommended Based on User Volume

| Concurrent Users | CPU       | Memory |
|------------------|-----------|--------|
| 50               | 8 threads | 16G    |
| 95               | 16 threads| 24G    |
| 135              | 24 threads| 32G    |

### Data Integration Performance

| Data Volume (Rows/Columns) | Extraction to Greenplum |
|----------------------------|-------------------------|
|1 million/9                | Approximately 6 seconds |
|10 million/9               | Approximately 39 seconds |
|100 million/9              | Approximately 5 minutes |
|1 billion/9                | Approximately 52 minutes |

* The data extraction speed is greatly affected by network speed and disk I/O performance. In this test, the network bandwidth from the business database to the Greenplum database was 4.9 Gbits/sec, and the disks were all SSB network drives.

## Installation File Preparation

Before installation, please download the Hengshi installation package `hengshi-sense-<version>.zip` and extract it into the `hengshi-<version>` directory.

```sh
mkdir hengshi-sense-<version> && unzip -qd hengshi-sense-<version>/ hengshi-sense-<version>.zip
```
