This package copies over logic and code from Neos 8.3/9.0 but changes how the connection to redis will be made. The new approach utilizes a lazy connection with retries enabled. Also connections are created as persistent connections. This should give redis and the network connection opportunities to recover if there should be short term connection issues or a stalled redis.
This might be better or worse for your infrastructure and we cannot predict what is better for you. We made this for use in Flownative Beach but probably most Kubernetes environments will benefit from this. In the long run we should provide these changes within Neos.Flow.
composer require flownative/redis-backend
In your Caches.yaml replace
backend: 'Neos\Cache\Backend\RedisBackend'
with
backend: 'Flownative\RedisBackend\RedisBackend'
All options remain the same.
