I have a scenario where application need to to get operation from redis around 80 times per request. When I am hitting 1 request on that application it gives response in less than 1 seconds but when increased the request size to 100 redissonClient starts behaving slowly and takes around 13 seconds to fetch 250 records.

I am new to redis and unsure if this is default. Though I found out in some article saying redis can handle millions of operation in 1 second on 1 node. Our redis server is running on 1 node currently.

Below is the redis configuration:

"singleServerConfig": 
 "idleConnectionTimeout": 10000,
 "pingTimeout": 1000,
 "connectTimeout": 10000,
 "timeout": 2000,
 "retryAttempts": 3,
 "retryInterval": 1500,
 "reconnectionTimeout": 2000,
 "failedAttempts": 3,
 "password": null,
 "subscriptionsPerConnection": 5,
 "clientName": null,
 "address": "redis://172.18.17.207:6379",
 "subscriptionConnectionMinimumIdleSize": 1,
 "subscriptionConnectionPoolSize": 50,
 "connectionMinimumIdleSize": 32,
 "connectionPoolSize": 100,
 "database": 0,
 "dnsMonitoringInterval": 5000
,
"threads": 128,
"nettyThreads": 128,
"codec": null,
"useLinuxNativeEpoll": false

And below is how I am instantiating redisson client at the time of startup:

try 
 Config config = Config.fromJSON(CommonConstants.REDIS_SINGLE_CONFIG_JSON_FILE);
 redisClient = Redisson.create(config);
 catch (IOException e) 
 log.error(null, "Error establishing connection to Redis Cluster!", e);
 

And below is how I am fetching records:

public List<Map<String, String>> fetch(List<String> ids) 
 return ids.stream().map(id -> 
 Map<String, String> m = redisClient.getMapCache(id);
 return m;
 ).collect(Collectors.toList());

I suspect I have wrongly configured redis client but could not figure out what is that.

Any help/light is much appreciated.

Thanks

Stream uses iterator provided by RMapCache object. It fetches only 10 elements by default, I would recommend you to use RMapCache.readAllMap method instead.
