是否可以使用 Spring Data Redis 使用 Lettuce 查找不同分片上的键

Question

我在我的 api 中使用 spring data redis。我正在尝试通过 java 运行以下命令：

Set<String> union = redisTemplate.opsForSet().union(ids);

这导致请求中的 CROSSSLOT 键不会散列到同一插槽错误，因为我正在搜索的键位于不同的分片上。

我的 Redis 数据库模型具有我正在尝试查找的键的 SET 数据模型。

有什么方法 Lettuce 可以跨分片找到密钥，我可以避免这个错误。我的 LettuceConnectionFactory 是这样的：

@Bean
    public LettuceConnectionFactory redisConnectionFactory() {
        RedisStandaloneConfiguration redisStandaloneConfiguration = new RedisStandaloneConfiguration();
        redisStandaloneConfiguration.setPort(port);
        redisStandaloneConfiguration.setHostName(host);
        redisStandaloneConfiguration.setDatabase(database);
        if (StringUtils.isNotBlank(password)) redisStandaloneConfiguration.setPassword(password);

        LettuceClientConfiguration.LettuceClientConfigurationBuilder builder = LettuceClientConfiguration.builder();
        if (useSSl) {
            builder.useSsl();
        }

        LettuceClientConfiguration clientConfiguration = builder
                .commandTimeout(Duration.ofSeconds(redisTimeoutMillis))
                .clientOptions(ClientOptions
                        .builder()
                        .disconnectedBehavior(ClientOptions.DisconnectedBehavior.REJECT_COMMANDS)
                        .build())
                .build();

        LettuceConnectionFactory connectionFactory = new LettuceConnectionFactory(redisStandaloneConfiguration, clientConfiguration);
        connectionFactory.afterPropertiesSet();

        return connectionFactory;
    }

    @Bean
    public RedisTemplate<String, Object> redisTemplate() {
        RedisTemplate<String, Object> template = new RedisTemplate<>();
        template.setConnectionFactory(redisConnectionFactory());
        return template;
    }

另外，是否可以避免联合操作并使用 org.springframework.data.repository.CrudRepository findAllByIds(ids) 获得相同的输出？

Answer 1

经过大量研究后，我找到了一些关于为什么您在 Redis 中遇到此 CROSSSLOT 错误的信息。

有一个关于 CROSSSLOT KEYS 问题的很好的解释性博客here。请阅读它。

从该博客可以得出以下结论。

错误原因：

当您尝试执行涉及以下操作的操作时，会出现此错误 Redis Cluster 中有多个键，但这些键不属于相同的哈希槽。

建议您可以采取的可能解决方案来缓解该问题：

使用单节点配置。这将确保所有密钥都位于单个节点中，从而完全消除 CROSSSLOT 密钥问题。
优化您的实体模型以减少多键操作的需要，因为 Redis 将无法维护这一点。
您可以在密钥内使用标签。 优点：假设您有多个密钥，现在您将它们附加到相同的标签，那么这将确保多个密钥进入同一个哈希槽，从而减少跨槽操作。

阅读博客以获取信息。

遵循下面给出的这些 Github 问题以供参考：

首先，不要被关键字“Spring OAuth2”的使用误导。这个问题和你面临的问题是一样的。

注意：槽！=碎片

我想提的主要事情是，多个哈希槽是由分片内的键创建的，并且不允许通过交叉操作从多个槽中获取它们。

现在，通过查看代码，我猜您很可能正在使用单节点配置。所以，请停止运行redis的集群模式。

现在来回答这个问题

另外，是否可以避免联合操作并使用 org.springframework.data.repository.CrudRepository findAllByIds(ids) 得到相同的输出？

是的，可以通过Redis-OM for Spring库和Redis Stack Server来实现，它具有搜索和查询的增强功能。

官方Redis-OM文档说：

Redis OM Spring 提供强大的存储库和自定义对象映射构建在令人惊叹的 Spring Data Redis (SDR) 之上的抽象框架。

现在，逐步进行：

根据操作系统从这里下载Redis Stack。
解压下载的zip并进入redis stack的bin文件夹并执行可执行文件redis-stack-server。

注意：我使用 macOS、Java 17、Spring Boot 2.7.x 和 Redis 7.2.1 来演示这一点。

打开两个终端，分别在每个终端上运行 redis-stack-server 文件和 redis-cli 文件。
现在，在 CLI 模式下，输入命令
```
MONITOR
```
。开始跟踪 Redis 服务器上发生的任何活动。
来到代码库：

我借助他们的 Redis-OM Spring 散列教程来展示它是如何工作的

您需要将

redis-om-spring

和

spring-boot-starter-data-redis

作为依赖项包含在 POM 中。

创业班：

@SpringBootApplication
@EnableRedisEnhancedRepositories
public class TestRedisSpringApplication {

    public static void main(String[] args) {
        SpringApplication.run(TestRedisSpringApplication.class, args);
    }

}

您必须使用

@EnableRedisEnhancedRepositories

使用基于 redis 的模型来检测存储库的存在。

存储库类：

@Repository
public interface PersonRepository extends CrudRepository<Person, String> {
}

实体类：

import com.redis.om.spring.annotations.Indexed;
import lombok.Data;
import lombok.NonNull;
import org.springframework.data.annotation.Id;
import org.springframework.data.redis.core.RedisHash;

@Data
@RedisHash
public class Person {
    @Id
    private String id;

    @NonNull
    @Indexed
    private String fullName;

    @NonNull
    @Indexed
    private String job;
}

注意：

@RedisHash

、

@Indexed

是来自 Redis-OM lib 的注释，它与 Redis Stack Server 一起使用，因为它对普通 Redis Server 缺乏的搜索和查询具有广泛的支持。

自定义 Redis 配置，保证创建

JedisConnectionFactory

的 bean，从而将其提供给 Redis-OM，并且必须提供该 bean。

@Configuration
public class CustomRedisConfiguration {

    @Bean
    public JedisConnectionFactory jedisConnectionFactory() {
        RedisStandaloneConfiguration redisConf = new RedisStandaloneConfiguration();
        redisConf.setHostName("localhost");
        redisConf.setPort(6379);
        JedisClientConfiguration conf = JedisClientConfiguration.builder()
                .readTimeout(Duration.ofMillis(1000))
                .connectTimeout(Duration.ofMillis(1000))
                .build();
        return new JedisConnectionFactory(redisConf, conf);
    }

}

服务器启动成功。
