We have made sure in the past that RedisInsight works with Garnet. Let us know if you run into any issues.

Currently, garnet is operated in cluster mode and is being used as a master slave structure.
When establishing a connection using intellij's Database function, the connection is established normally, but the schema is not viewed.

The versions used are as follows:
IntelliJ IDEA 2023.2.5
garnet : 1.0.8

The script used is as follows.

./GarnetServer --cluster --checkpointdir='/data/' --aof

redis-cli -h garnet-m -p 6379 cluster addslots $(seq 0 16383);
redis-cli -h garnet-m -p 6379 cluster set-config-epoch 1;
redis-cli -h garnet-s1 -p 6379 cluster set-config-epoch 2;
redis-cli -h garnet-s2 -p 6379 cluster set-config-epoch 3;
redis-cli -h garnet-m -p 6379 cluster meet garnet-s1 6379;
redis-cli -h garnet-m -p 6379 cluster meet garnet-s2 6379;
redis-cli -h garnet-s1 -p 6379 cluster replicate $(redis-cli -h garnet-m -p 6379 cluster myid);
redis-cli -h garnet-s2 -p 6379 cluster replicate $(redis-cli -h garnet-m -p 6379 cluster myid);

We confirmed that when applying the settings, data replication proceeds without problem.
However, the schema is not being searched.

And when using Redis Insight, the connection itself is not established.

Is there a problem with the method I used?

we have not tried with cluster, if you can debug and let us know which command is missing, we might be able to add it. cc @vazois

Sorry for the late reply.
When executing the CONFIG GET databases command, I confirmed that an error occurred because the result type was different.
The log is as follows.

CONFIG GET databases

Based on redis 7.2.3 version, the result is output as follows.

1) "databases"
2) "1"

However, garnet is output as follows:

"16"

Good work narrowing it down, this should not be hard to fix. Thanks.

Thanks for providing a repro. Fix for this here #389.

@kyuminMoon - can you see if this makes your tool work or does it hit some other issue after this fix?

@badrishc Thank you for the quick response
After testing with intellij and datagrip, it was confirmed that it was working properly!
