sandynz opened a new issue, #19803:
URL: https://github.com/apache/shardingsphere/issues/19803

   ## Bug Report
   
   ### Which version of ShardingSphere did you use?
   master branch, fbbc52c149e1f146803fb829670188c195cb3b20
   
   ### Which project did you use? ShardingSphere-JDBC or ShardingSphere-Proxy?
   Proxy
   
   ### Expected behavior
   global properties of server.yaml won't be removed in registry center after executing `SET VARIABLE ...`
   
   ### Actual behavior
   Initial `props` value:
   ```
   proxy-frontend-flush-threshold: 128
   proxy-frontend-executor-size: 0
   proxy-frontend-max-connections: 0
   proxy-mysql-default-version: 5.7.22
   proxy-backend-driver-type: JDBC
   proxy-backend-query-fetch-size: -1
   kernel-executor-size: 16
   proxy-netty-backlog: 1024
   proxy-default-port: 3307
   proxy-backend-executor-suitable: OLAP
   proxy-hint-enabled: false
   sql-show: false
   sql-federation-enabled: false
   max-connections-size-per-query: 1
   check-table-metadata-enabled: false
   ```
   
   After executing `SET VARIABLE sql_show = true;`
   `props` value is:
   ```
   sql-show: true
   ```
   
   ### Reason analyze (If you can)
   
   <img width="1351" alt="图片" src="https://user-images.githubusercontent.com/42492540/182338663-aa2c39f2-26ba-433e-8465-c181100b4f03.png">
   In fact, `metaDataContexts.getMetaData().getProps().getProps()` has 15 properties, but `new Properties(metaDataContexts.getMetaData().getProps().getProps())` has 0 properties, since the Properties constructor parameter is defaults:
   ```
       public Properties(Properties defaults) {
           this.defaults = defaults;
       }
   ```
   
   ### Steps to reproduce the behavior, such as: SQL to execute, sharding rule configuration, when exception occur etc.
   
   1, Start proxy.
   2, Login proxy and run `SET VARIABLE sql_show = true;`
   3, Check `props` in registry center.
   
   ### Example codes for reproduce this issue (such as a github link).
