I have a (paid) redis-labs instance. how can I use redis-json features on top of it?
Also, can I use normal redis-commands in a redis which has redis-json module installed?
It depends if you are using Redis Enterprise or Redis Enterprise Cloud
Redis Enterprise Cloud: https://docs.redislabs.com/latest/rc/databases/create-database/
Redis Enterprise: https://docs.redislabs.com/latest/modules/add-module-to-database/
or follow this quickstart: https://docs.redislabs.com/latest/modules/redisjson/redisjson-quickstart/
Also, can I use normal redis-commands in a redis which has redis-json
module installed?
Yes, all Redis commands will be available (RedisJSON extends Redis)

My ElastiCache Redis version is on 6.0.5. But I want to use 6.2. According to AWS you can't specify the exact v6.x version.
I want to know if it's possible to upgrade it manually or something.
I’ve looked into this and was unable to find a way to use ElastiCache with Redis 6.2. Instead, I have deployed Redis in docker with ECS and Fargate in a Redis 6.2 dockerfile. Not as turnkey as ElastiCache though, I’m afraid.
Originally was trying to install RediSearch ontop of Aws ElastiCache but it seems they dont support modules in their managed service (makes sense).
Then I was looking into running RediSearch on a separate EC2 instance with my VPC instance that would allow me to utilize it while not having to install it in ElastiCache directly.
Is this possible?
Thanks!
RediSearch is available as a service on Redis Enterprise Cloud from Redis Labs on AWS, Azure and GCP.
Can anyone explain to me what is aware client in Redis Enterprise ?
I found this post: Redis Enterprise Clustering Command Error 'CLUSTER'
I try to use Redis Enterprise Cluster with docker.
I create 3 docker redis nodes with two shards for better scalability.
So what exactly is that aware client and what is the difference between non-cluster aware ?
Also, what is regular OSS cluster ?
Thank You..
"Cluster Aware" means a Redis client that supports the OSS Cluster API (https://redis.io/topics/cluster-spec). For example, the Ruby client https://github.com/redis/redis-rb#cluster-support supports it.
A non-aware client is a client that only supports connecting to Redis in single-instance mode (and perhaps Sentinel), such as the Python client https://github.com/andymccurdy/redis-py.
The Enterprise Cluster can be used by both types of clients regardless of how the database is deployed (i.e. clustered or not).
To clear some more of the confusion:
OSS Cluster - a mode of deployment and API (i.e. not single-instance)
Enterprise Cluster - a product
I was wondering why do we need Redis server for running CKAN.
If needed, why? And How do I configure it with CKAN?
p.s
I am running my ckan instance in RHEL7.
Update: Redis has been a requirement since CKAN 2.7, when a new system for asynchronous background jobs was introduced which relies on Redis. You can configure the Redis connection using the ckan.redis.url option.
Redis is not required for the current version of CKAN (2.6.2 at the time of this writing), it's not even mentioned in the CKAN 2.6.2 documentation.
However, the upcoming 2.7 release will require Redis for its new system of asynchronous background jobs. Redis will be configured using the new ckan.redis.url option.
I just started evaluating Redis. I am using Redis 2.8.19 which the most latest stable release. Redis 2.9 is still unstable and Redis 3.0 is just available for developer's preview (not recommended for production). I was tryin to setus a cluster of Redis and when I changed my redis.conf and appended
cluster-enabled yes
cluster-config-file nodes.conf
cluster-node-timeout 5000
and started my Redis server by
src/redis-server ./redis.conf
it gave me an error as follows
* FATAL CONFIG FILE ERROR *
Reading the configuration file, at line 2
'cluster-enabled yes'
Bad directive or wrong number of arguments
I googled the error and got to know that my version (2.8.19) does not support cluster. I was still unable to fine any such specification in Redis Docs. My question is simple. Does Redis 2.8.19 supports redis cluster configuration? Or I have to upgrade to Redis 2.9 or Redis 3.0. I am evaluating Redis because I need to deploy it in production. Please guide.
Redis Cluster support is only for versions >= 3.0.0. Redis 3.0.0 will be released as a stable version in a matter of days, it's a good idea to use it if you want to use Cluster. The cluster support is considered to be stable, however for it to be considered mature we want to see adoption. Btw there is already at least a very large site using it in production. Currently the most sane thing to do if you need Redis Cluster is to test it for your use case, and if it looks great, use it.
Redis cluster is supported only in Redis 3.0+ (which is now stable). I have written a simple API called "Simple Redis Cluster Client" which can be used in redis's sub 3.0 versions for running in a cluster like mode (Not precisely a cluster, it just distributes keys among redis nodes based on the key's hashcode, You can have a look # https://github.com/prash-mi/simple-redis-cluster-client
Cluster support for Redis is only from v3 - v2.8.19 doesn't do clustering.
