 kernel-executor-size: 16  # Infinite by default.
 proxy-frontend-flush-threshold: 128  # The default value is 128.
 # sql-show is the same as props in logger ShardingSphere-SQL, and its priority is lower than logging rule
 sql-show: false
 check-table-metadata-enabled: false
   # Proxy backend query fetch size. A larger value may increase the memory usage of ShardingSphere Proxy.
   # The default value is -1, which means set the minimum value for different JDBC drivers.
 proxy-backend-query-fetch-size: -1
 proxy-frontend-executor-size: 0 # Proxy frontend executor size. The default value is 0, which means let Netty decide.
