枚举 RocksDBProperty

java.lang.Object

java.lang.Enum<RocksDBProperty>

org.apache.flink.contrib.streaming.state.RocksDBProperty

所有已实现的接口:

Serializable, Comparable<RocksDBProperty>

@Internal
public enum RocksDBProperty
extends Enum<RocksDBProperty>

RocksDB properties that can be queried by Flink's metrics reporter.

Note: Metrics properties are added in each new version of RocksDB, when upgrading to a latter version consider updating this class with newly added properties.

方法详细资料

values

public static RocksDBProperty[] 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 (RocksDBProperty c : RocksDBProperty.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 RocksDBProperty 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

getRocksDBProperty

public String getRocksDBProperty()

返回:

property string that can be used to query RocksDB.getLongProperty(ColumnFamilyHandle, String).

getConfigKey

public String getConfigKey()

返回:

key for enabling metric using Configuration.
