Laravel 8 and the dev environment is Sail - including Redis.
The .env file:
CACHE_DRIVER=redis
..
REDIS_HOST=redis
REDIS_PASSWORD=null
REDIS_PORT=6379
Using the Redis facade functions, like
Redis::set( 'bar', 'The hole of the moon' );
using redis-cli is possible to find the value stored in cache
but using
Cache::put('bar2', 'baz', 100);
or even
Cache::store('redis')->put('bar3', 'Awesome', 100);
the values cannot be seen using the redis console
Actually, data is onRedis server...
A nice explanation here: Redis keys not shown while using Cache facade in Laravel

I am trying to connect to my Redis instance from a groovy script (ExecuteGroovyScript) and execute arbitrary commands such as LPUSH. I currently have RedisConnectionPoolService enabled and working fine for caching processors.
Is there any way to achieve this? Any examples are appreciated.
EDIT:
I got to the point where I can call a command but for some reason it fails, here is the code and error
service = context.getControllerServiceLookup().getControllerService("2b841623-35ed-1e1a-0a77-46087267939d")
service.getConnection().withCloseable { redis ->
redis.listCommands().lPush("key".getBytes(), "1".getBytes())
}
If you have a RedisConnectionPoolService called service and call service.getConnection(), you will have a Spring Redis RedisConnection instance, so you can check their API for the kinds of calls you can make.
For LPUSH specifically you can call service.getConnection().listCommands().lpush()
I am trying to use Geode Redis Adapter as my server for Rate Limiting provided by Spring Cloud Gateway. If I use a real Redis Server, everything works perfectly, but with Geode Redis Adapter doesn't.
I am not too sure if this functionality is supported.
I tried to start a [Geode image] (https://hub.docker.com/r/apachegeode/geode/) exposing the default Redis port 6739. Starting the container, I executed using gfsh the following commands:
start server --name=redis --redis-port=6379 --J=-Dgemfireredis.regiontype=PARTITION_PERSISTENT
When I try to access in my local machine by redis-cli -h localhost -p 6379 I can get connected.
My implementation is simple:
application.yaml
- id: rate-limitter
predicates:
- Path=${GUI_CONTEXT_PATH:/rate-limit}
- Host=${APP_HOST:localhost:8080}
filters:
- name: RequestRateLimiter
args:
key-resolver: "#{#remoteAddrKeyResolve}"
redis-rate-limiter:
replenishRate: ${rate.limit.replenishRate:1}
burstCapacity: ${rate.limit.burstCapacity:2}
uri: ${APP_HOST:localhost:8080}
Application.java
#Bean
KeyResolver remoteAddrKeyResolve() {
return exchange -> Mono.just(exchange.getSession().subscribe().toString());
}
When my application is started and I try to access /rate-limit, I expected to connect to redis and my page be displayed.
However, my Spring application keeps trying to access and can't i.l.c.p.ReconnectionHandler: Reconnected to localhost:6379. So, the page is not displayed and keep loading. FIXED in Edit1 below
Problem is I am using RedisRateLimiter and tried to simulate the access with a for loop. Checking the RedisRateLimiter.REMAINING_HEADER, the value is -1 always. Doesn't seems right, because I don't have this issue in Redis itself.
During the start of the application, I also receive these messages on connection to Geode Redis Adapter:
Starting without optional epoll library
Starting without optional kqueue library
Is anything missing in my Geode Redis Adapter or anything else in Spring?
Thank you
Edit 1: I was missing to start the locator and region, that's why I wasn't able to connect.
start locator --name=locator
start server --name=redis --redis-port=6379 --J=-Dgemfireredis.regiontype=PARTITION_PERSISTENT
create region --name=redis-region --type=REPLICATE_PERSISTENT
I have a question about connecting Redis DB to Jmeter, using jp#gc - Redis Data Set.
I created a test and want to see a value from Redis, the problem is that When I add the Redis DB component nothing happened, I press the Play button and nothing happened.
I think I am not configured the Redis as expected in jmeter.
I didnt create any variable just name a new variable called dsos.
I just want to pass the value from redis of dsos_13_173 to the parameter dsos
1. How can I see why the configuration not succeed?
2. What I am missing?
I am using jmeter 3.2, with plugin v0.2 and installed it from plug in manager, and the DB is remote I am using IP not localhost as in all examples
Regards
Redis Data Set config acts alike CSV Data Set Config, so given you want to use the data from Redis in i.e. HTTP Request sampler you just need to refer to it as ${dsos} where required.
You can also double check the associated JMeter Variable value using Debug Sampler
See JMeter’s Redis Data Set - An Introduction for comprehensive explanation, step-by-step instruction and example test plan.
Currently i have plan a process of using a script to add key values into redis using rpush.
I am currently using bin/sh to launch redis.
But what is the syntax to rpush my keyvalue into redis server.
#!/bin/sh
redis-cli -h 172.16.114.54
rpush stlfile "fad.stl" // how to rpush in with the correct syntax?
What kind of language is more suitable for redis so maybe i could change now to ease my future processes
Seems like using python would be easier to code Redis
from this post i found here i can easily install python.
ImportError: No module named redis
i managed to create a python script with this
import redis
r = redis.StrictRedis(host='172.16.114.54', port=6379, db=0)
r.lpush ('stlfile', 'variable.stl')
r.lrange ('stlfile', 0, -1)
when checked with another client i managed to see variable.stl went in :D
I am using Spring Jedis Client to use Redis in my application. I want to rename the commands so that no one else can fire the same just in case they are able to connect to my server.
Can anyone give an example of how to use rename command from Jedis and then how to fire subsequent commands using the the modified one ?
You can't rename a Redis command yet w/o changing the config file issue #640.
Even if you add the rename-command config file directive and restart your Redis, Jedis doesn't seem to allow sending arbitrary commands easily or to provide a trivial (i.e. no code changes) way to rename them.
What you could do, however, if you're really insistent on renaming a command and then calling it from Jedis is EVAL it. This will probably go in my pantheon of ugly hacks (:)) but after adding rename-command get foo to my /etc/redis/redis.conf and doing service redis-server restart look what I can do:
$ redis-cli
redis 127.0.0.1:6379> set bar baz
OK
redis 127.0.0.1:6379> get bar
(error) ERR unknown command 'get'
redis 127.0.0.1:6379> foo bar
"baz"
redis 127.0.0.1:6379> eval "return(redis.call('get', KEYS[1]))" 1 bar
(error) ERR Error running script (call to f_db0e060e4f58231d51f21685b20ff847de8ab9e1): Unknown Redis command called from Lua script
redis 127.0.0.1:6379> eval "return(redis.call('foo', KEYS[1]))" 1 bar
"baz"
redis 127.0.0.1:6379>
Of course, if you take this route your code can get pretty messy in no time at all so be careful where you tread... Good luck!
If a malicious user connects directly to Redis, then one can access all opcodes.
There is no feature in the Redis library to rename commands. Even if you expose access to a custom API that renames commands, you cannot change the inner opcodes of Redis itself.
Edit:
You're right, it is possible to rename commands by changing the config file indeed!
After you set the new command names, you have to recompile Jedis.
First rename the enum on src/main/java/redis/clients/jedis/Protocol.java, line 203.
Now find the corresponding enum usage on src/main/java/redis/clients/jedis/BinaryClient.java and change it also.
It may be sufficient: everywhere you still keep the old command java interfaces (e.g. zadd etc.), and inside Jedis it will talk to Redis calling the renamed command.
Is that your intention ?
