Information security - threat detection engine - common rule engine base performance comparison
2022-07-06 15:47:00 【Empty one by one】
Recently, we need to use rule engine to do data processing and threat detection engine , Therefore, several technical solutions commonly used by common centralized rule engines in the market have been investigated , I use the same rules ,
Business rules ：
The order amount is less than 100, Give points 0;
Order amount (100,500], Give points 100;
Order amount (500,1000], Give points 500;
Order amount (1000,+&], Give points 1000;
Use the following rule engine to execute 100 Ten thousand times 、1000 Ten thousand times 、5000 Ten thousand times , Each scenario executes 3 Take the average value every time to get the results in the following table , From the performance test results ,groovy Win , Best performance .
| Number of executions \ Rules engine | QLExpression (ms) | groovy （ms） | drools (ms) | v8 |
|---|---|---|---|---|
| 100w | 1590 | 171 | 364 | NA |
| 1000w | 12551 | 709 | 3530 | NA |
| 5000w | 60230 | 3516 | 19414 | NA |
because v8 use js code , Execution performance is low , Not included for comparison ;
| Rules engine | QLExpression | groovy | drools |
|---|---|---|---|
| Dynamic rules | Support | Support | Support |
| flexibility | low | high | in |
| Complexity | low | high | in |
| Get started | fast | slow | slow |
| Use breadth | in | in | high |
All three rule engines support dynamic rules , Can be provided by api Dynamically extend rules , In terms of flexibility groovy and drools Support scripting , There are common packaging schemes on the market ; among QL Widely used in small and medium-sized enterprises, familiar with java For the contestants, it is basically out of the box ,groovy and drools As a rule engine, it is widely used in Internet enterprises , There are certain learning and training costs ,drools More followers, wider application area ;
The core test code is as follows
