枚举常量详细资料

NRT

public static final Replica.Type NRT

Writes updates to transaction log and indexes locally. Replicas of type NRT support NRT (soft commits) and RTG. Any NRT replica can become a leader. A shard leader will forward updates to all active NRT and TLOG replicas.

TLOG

public static final Replica.Type TLOG

Writes to transaction log, but not to index, uses replication. Any TLOG replica can become leader (by first applying all local transaction log elements). If a replica is of type TLOG but is also the leader, it will behave as a NRT. A shard leader will forward updates to all active NRT and TLOG replicas.

PULL

public static final Replica.Type PULL

Doesn’t index or writes to transaction log. Just replicates from NRT or TLOG replicas. PULL replicas can’t become shard leaders (i.e., if there are only pull replicas in the collection at some point, updates will fail same as if there is no leaders, queries continue to work), so they don’t even participate in elections.

方法详细资料

values

public static Replica.Type[] 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 (Replica.Type c : Replica.Type.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 Replica.Type 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

get

public static Replica.Type get(String name)
