- 枚举常量详细资料
  - SQL_SHOW
```
public static final ConfigurationPropertyKey SQL_SHOW
```
    Whether show SQL in log.
  - SQL_SIMPLE
```
public static final ConfigurationPropertyKey SQL_SIMPLE
```
    Whether show SQL details in simple style.
  - KERNEL_EXECUTOR_SIZE
```
public static final ConfigurationPropertyKey KERNEL_EXECUTOR_SIZE
```
    The max thread size of worker group to execute SQL.
  - MAX_CONNECTIONS_SIZE_PER_QUERY
```
public static final ConfigurationPropertyKey MAX_CONNECTIONS_SIZE_PER_QUERY
```
    Max opened connection size for each query.
  - CHECK_TABLE_METADATA_ENABLED
```
public static final ConfigurationPropertyKey CHECK_TABLE_METADATA_ENABLED
```
    Whether validate table meta data consistency when application startup or updated.
  - SQL_FEDERATION_ENABLED
```
public static final ConfigurationPropertyKey SQL_FEDERATION_ENABLED
```
    Whether enable SQL federation.
  - PROXY_FRONTEND_DATABASE_PROTOCOL_TYPE
```
public static final ConfigurationPropertyKey PROXY_FRONTEND_DATABASE_PROTOCOL_TYPE
```
    Frontend database protocol type for ShardingSphere-Proxy.
  - PROXY_FRONTEND_FLUSH_THRESHOLD
```
public static final ConfigurationPropertyKey PROXY_FRONTEND_FLUSH_THRESHOLD
```
    Flush threshold for every records from databases for ShardingSphere-Proxy.
  - PROXY_HINT_ENABLED
```
public static final ConfigurationPropertyKey PROXY_HINT_ENABLED
```
    Whether enable hint for ShardingSphere-Proxy.
  - PROXY_BACKEND_QUERY_FETCH_SIZE
```
public static final ConfigurationPropertyKey PROXY_BACKEND_QUERY_FETCH_SIZE
```
    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_FRONTEND_EXECUTOR_SIZE
```
public static final ConfigurationPropertyKey PROXY_FRONTEND_EXECUTOR_SIZE
```
    Proxy frontend executor size. The default value is 0, which means let Netty decide.
  - PROXY_BACKEND_EXECUTOR_SUITABLE
```
public static final ConfigurationPropertyKey PROXY_BACKEND_EXECUTOR_SUITABLE
```
    Available options of proxy backend executor suitable: OLAP(default), OLTP. The OLTP option may reduce time cost of writing packets to client, but it may increase the latency of SQL execution and block other clients if client connections are more than PROXY_FRONTEND_EXECUTOR_SIZE, especially executing slow SQL.
  - PROXY_FRONTEND_MAX_CONNECTIONS
```
public static final ConfigurationPropertyKey PROXY_FRONTEND_MAX_CONNECTIONS
```
    Less than or equal to 0 means no limitation.
  - PROXY_BACKEND_DRIVER_TYPE
```
public static final ConfigurationPropertyKey PROXY_BACKEND_DRIVER_TYPE
```
    Proxy backend driver type..
  - PROXY_MYSQL_DEFAULT_VERSION
```
public static final ConfigurationPropertyKey PROXY_MYSQL_DEFAULT_VERSION
```
    Proxy MySQL default version.
  - PROXY_DEFAULT_PORT
```
public static final ConfigurationPropertyKey PROXY_DEFAULT_PORT
```
    Proxy default start port.
  - PROXY_NETTY_BACKLOG
```
public static final ConfigurationPropertyKey PROXY_NETTY_BACKLOG
```
    Proxy Netty backlog size.
  - PROXY_INSTANCE_TYPE
```
public static final ConfigurationPropertyKey PROXY_INSTANCE_TYPE
```
    Proxy instance type.
- 方法详细资料
  - values
```
public static ConfigurationPropertyKey[] values()
```
    按照声明该枚举类型的常量的顺序, 返回包含这些常量的数组。该方法可用于迭代常量, 如下所示:
```
for (ConfigurationPropertyKey c : ConfigurationPropertyKey.values())
    System.out.println(c);
```
    返回:
    
    按照声明该枚举类型的常量的顺序返回的包含这些常量的数组
  - valueOf
```
public static ConfigurationPropertyKey valueOf(String name)
```
    返回带有指定名称的该类型的枚举常量。字符串必须与用于声明该类型的枚举常量的标识符完全匹配。(不允许有多余的空格字符。)
    
    参数:
    
    name - 要返回的枚举常量的名称。
    
    返回:
    
    返回带有指定名称的枚举常量
    
    抛出:
    
    IllegalArgumentException - 如果该枚举类型没有带有指定名称的常量
    
    NullPointerException - 如果参数为空值
  - getKeyNames
```
public static Collection<String> getKeyNames()
```
    Get property key names.
    
    返回:
    
    collection of key names
