Jedis and Lettuce async abilities

by

There is no one answer to your question because it depends. Jedis and lettuce are both mature clients. To complete the list of Java clients, there is also Redisson, which adds another layer of abstraction (Collection/Queue/Lock/… interfaces instead of raw Redis commands). It pretty much depends on how you’re working with the clients. In general, … Read more

How Jedis Pool works?

You haven’t configured the maxTotal size of the pool, and the default value is only 8. You could change the JedisFactory constructor to: public JedisFactory() { JedisPoolConfig poolConfig = new JedisPoolConfig(); poolConfig.setMaxTotal(128); jedisPool = new JedisPool(poolConfig, RedisDBConfig.HOST, RedisDBConfig.PORT, RedisDBConfig.TIMEOUT, RedisDBConfig.PASSWORD); } Beware also of the default value of the WhenExhaustedAction (WHEN_EXHAUSTED_BLOCK), as it may not … Read more

Why is data getting stored with weird keys in Redis when using Jedis with Spring Data?

by

Ok, googled around for a while and found help at http://java.dzone.com/articles/spring-data-redis. It happened because of Java serialization. The key serializer for redisTemplate needs to be configured to StringRedisSerializer i.e. like this: <bean id=”jedisConnectionFactory” class=”org.springframework.data.redis.connection.jedis.JedisConnectionFactory” p:host-name=”${redis.server}” p:port=”${redis.port}” p:use-pool=”true”/> <bean id=”stringRedisSerializer” class=”org.springframework.data.redis.serializer.StringRedisSerializer”/> <bean id=”redisTemplate” class=”org.springframework.data.redis.core.RedisTemplate” p:connection-factory-ref=”jedisConnectionFactory” p:keySerializer-ref=”stringRedisSerializer” p:hashKeySerializer-ref=”stringRedisSerializer” /> Now the key in redis is vc:501381.
