            Redisson Hibernate 2L cache setup but always executes SQL query
            Asked 2022-Mar-08 at 00:18

            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?

            Well 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.

            1st 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.

            Unable to connect to AWS ElastiCache form python client
            Asked 2021-Aug-22 at 21:11

            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:

            Apparently 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.

            How to get embedded Redis metrics?
            Asked 2021-Jun-14 at 08:47

            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 08:47

            Redis 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.

            1. install command line interface
              npm install -g redis-cli
            2. connect to redis running locally(cmd: rdcli -h host -p port -a password )
              rdcli -h localhost
            3. use any redis commands
              localhost:6379> info memory
