I am using Google cloud managed redis cluster(v5)
via redisson(3.12.5)
Following are my SingleServer
configurations in yaml file
singleServerConfig:
idleConnectionTimeout: 10000
connectTimeout: 10000
timeout: 3000
retryAttempts: 3
retryInterval: 1500
password: null
subscriptionsPerConnection: 5
clientName: null
address: "redis://127.0.0.1:6379"
subscriptionConnectionMinimumIdleSize: 1
subscriptionConnectionPoolSize: 50
connectionMinimumIdleSize: 40
connectionPoolSize: 250
database: 0
dnsMonitoringInterval: 5000
threads: 0
nettyThreads: 0
codec: !<org.redisson.codec.JsonJacksonCodec> {}
I am getting following exceptions when I increase the load on my application
org.redisson.client.RedisTimeoutException: Unable to acquire connection! Increase connection pool size and/or retryInterval settings Node source: NodeSource
org.redisson.client.RedisTimeoutException: Command still hasn't been written into connection! Increase nettyThreads and/or retryInterval settings. Payload size in bytes: 34. Node source: NodeSource
It seems there is no issue on redis cluster and i think i need to make tweaking in my client side redis connection pooling confs(mentioned above) to make it work.
Please suggest me the changes i need to make in my confs
I am also curious if I should close the Redis
connection after making get/set calls. I have tried finding this but found nothing conclusive on how to close Redis
connections
One last thing that I want to ask is that is there any mechanism to get Redis
connection pool stats(active connection, idle connection etc ) in Redisson
Edit1:
I have tried by changing values following values in 3 different iterations
Iteration 1:
idleConnectionTimeout: 30000
connectTimeout: 30000
timeout: 30000
Iteration 2:
nettyThreads: 0
Iteration 3:
connectionMinimumIdleSize: 100
connectionPoolSize: 750
I have tried these things but nothing has worked for me
Any help is appreciated.
Thanks in advance
Assuming you are getting low memory alerts on your cache JVM.
You may have to analyze the traffic and determine 2 things
Both can be determined by the traffic on your server.
For option 1 configuring pool-size would solve you issue, but for option 2 you may have to refactor your code to persist data in smaller chunks.
Try to set nettyThreads = 64
