[FR]: Redis sentinel cluster support for opik backend

[sayandigital]

Proposal summary

Redis cluster/sentinel configuration missing.Only config for single node and aws elasticcache in config.yml of opikbackend.

Does it support redis sentinel.
Example usage of redis sentinel .Is it configured in the single url

Redis configuration
redis:

Default: redis://:opik@localhost:6379/0

Description: single node redis's URL

singleNodeUrl: ${REDIS_URL:-redis://:opik@localhost:6379/0}

AWS IAM authentication configuration (optional)

When enabled, takes precedence over singleNodeUrl authentication

awsIamAuth:
# Default: false
# Description: Enable AWS IAM authentication for ElasticCache Redis
enabled: ${OPIK_REDIS_AWS_IAM_AUTH_ENABLED:-false}
# Description: AWS User ID for IAM authentication
awsUserId: ${OPIK_REDIS_AWS_USER_ID:-''}
# Default: us-east-1

Motivation

Standalone redis is not scalable beyond experimentation.

Does it support any other kv store other than redis/aws?

Thank you for your feature request regarding Redis Sentinel support. Currently, the Opik backend supports only single-node Redis configurations and AWS ElastiCache, as you've noted. However, the underlying library, Redisson, does support Redis Sentinel and Cluster configurations. Implementing these features would involve updating the RedisConfig.java to include Sentinel and Cluster configuration paths, alongside extending the configuration options in config.yml.

Regarding your question about other key-value stores, the Opik backend is currently designed to work with Redis as the key-value store. If there is significant interest or necessity, support for additional key-value stores could be considered for future development, but this would require architectural decisions from the maintainers.

If you have any more questions or need further assistance, please feel free to ask!
