QUESTION
I'm trying to setup Redisson Hibernate 2L caching but I'm seeing the hibernate query execute every time even though the results are clearly cached on my Redis instance.
When debugging I can see it goes through hibernate and does the query execution and then after it goes into the putIntoCache
from RedissonStorage.java
as expected. When I check Redis I can see the new cached values. However, on a subsequent call to my service it again goes through the hibernate executeQueryStatement
for the the exact same hibernate query but interestingly it then goes into the getFromCache
from RedissonStorage.java
and appears to return the value from Redis. Why is it executing the query every time and not actually checking redis first?

...ANSWER
Answered 2022-Mar-08 at 00:18Well looks like JPA caching will work for the default findById
but will not work for findAll
or a custom findByType
or in this case findByEmployeeId
.
However, I found a way to make it work by use of @QueryHints
.

QUESTION
i am using spring boot web flux with redisson. I want to enable all key expired event in my application. i tried it this way. but it doesn't work.
...ANSWER
Answered 2021-Sep-23 at 15:541st issue is, you haven't subscribed to the listener. and the 2nd one is that you can't use getTopic
to the pub-sub event if you use a pattern in redisson. you should use getPatternTopic
method like this. and make sure to subscribe to the process finally. and the listener should be implemented from PatternMessageListener
interface.
QUESTION
I have an AWS ElastiCache instance of 2 replicated nodes (cluster-mode disabled).
I am able to connect through my java client using redisson (a service running in the same cluster). However, when I'm using the python redis client, it does not seem to connect. Or it seems to connect but doesn't subscribe. I don't see any errors for connection, but when I subscribe to a pub/sub topic I don't get any acknowledgment as well. Not even the first message which returns 1
for the successful subscription. Not sure what I'm doing wrong.
Also it works if I'm connecting to a local redis instance. Below is the code:

I have just started with testing redisson client to connect to redis. By default it uses Debug level logging and writes a lot of logs. How can I increase the level of logging to INFO?

QUESTION
I'm working with socketio and netty with java and I'm new to both of them.
my client side code looks like this.
...ANSWER
Answered 2021-Jul-02 at 06:13Apparently it seems the problem is with the libraries. There is some compatibility issue with newer versions of socketio client library with netty dependencies for java and it is causing the weird problems.
My dependency for netty socketio is shown below which obviously is the latest as of answering this question.
QUESTION
I have used Embedded Redis for caching in my springboot application. The redis runs on localhost and default port "6379"
on application start up.
Is there a way to get metrics(memory-used, keyspace_hits, keyspace_misses, etc..) for embedded redis, from outside the application, may be command line or any API
?
PS: I have used Redisson as client to perform cache operations with redis.
Thanks.
...ANSWER
Answered 2021-Jun-14 at 08:47Redis has provided a command line interface : redis-cli
to interact with it and get the metrics. redis-cli can be used on embedded redis as well.
- install command line interface
npm install -g redis-cli - connect to redis running locally(cmd: rdcli -h host -p port -a password )
rdcli -h localhost - use any redis commands
localhost:6379> info memory

Install redisson
You can use redisson like any standard Java library. Please include the the jar files in your classpath. You can also use any IDE and you can run and debug the redisson component as you would do with any other Java program. Best practice is to use a build tool that supports dependency management such as Maven or Gradle. For Maven installation, please refer maven.apache.org. For Gradle installation, please refer gradle.org .
