枚举 Slice.State

java.lang.Object

java.lang.Enum<Slice.State>

org.apache.solr.common.cloud.Slice.State

所有已实现的接口:

Serializable, Comparable<Slice.State>

封闭类:

Slice

public static enum Slice.State
extends Enum<Slice.State>

The slice's state.

枚举常量概要

枚举常量

枚举常量和说明
ACTIVE The normal/default state of a shard.
CONSTRUCTION When a shard is split, the new sub-shards are put in that state while the split operation is in progress.
INACTIVE A shard is put in that state after it has been successfully split.
RECOVERY Sub-shards of a split shard are put in that state, when they need to create replicas in order to meet the collection's replication factor.
RECOVERY_FAILED Sub-shards of a split shard are put in that state when the split is deemed failed by the overseer even though all replicas are active because either the leader node is no longer live or has a different ephemeral owner (zk session id).

枚举常量详细资料

ACTIVE

public static final Slice.State ACTIVE

The normal/default state of a shard.

INACTIVE

public static final Slice.State INACTIVE

A shard is put in that state after it has been successfully split. See the reference guide for more details.

CONSTRUCTION

public static final Slice.State CONSTRUCTION

When a shard is split, the new sub-shards are put in that state while the split operation is in progress. It's also used when the shard is undergoing data restoration. A shard in this state still receives update requests from the parent shard leader, however does not participate in distributed search.

RECOVERY

public static final Slice.State RECOVERY

Sub-shards of a split shard are put in that state, when they need to create replicas in order to meet the collection's replication factor. A shard in that state still receives update requests from the parent shard leader, however does not participate in distributed search.

RECOVERY_FAILED

public static final Slice.State RECOVERY_FAILED

Sub-shards of a split shard are put in that state when the split is deemed failed by the overseer even though all replicas are active because either the leader node is no longer live or has a different ephemeral owner (zk session id). Such conditions can potentially lead to data loss. See SOLR-9438 for details. A shard in that state will neither receive update requests from the parent shard leader, nor participate in distributed search.

方法详细资料

values

public static Slice.State[] 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 (Slice.State c : Slice.State.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 Slice.State 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

toString

public String toString()

覆盖:

toString 在类中 Enum<Slice.State>

getState

public static Slice.State getState(String stateStr)

Converts the state string to a State instance.
