## Question
**For English only**, other languages will not accept.
Before asking a question, make sure you have:
- Googled your question.
- Searched open and closed [GitHub issues](https://github.com/apache/shardingsphere/issues).
- Read documentation: [ShardingSphere Doc](https://shardingsphere.apache.org/document/current/en/overview).
Please pay attention on issues you submitted, because we maybe need more details.
If no response **more than 7 days** and we cannot reproduce it on current information, we will **close it**.
when i create a custom algorithm implementation class, I start sharding-proxy(4.1.0), but i found it init 2 times, why? and if it init 1 time by every process？
