Regarding Redis configuration files and caching duration.

[snehasish behera]

Hi,

I just wanted to know about some few topics regarding redis. 

1) How to write a config file for Redis enterprise?

2) What is the default caching time in redis and how to change it?

Thanks,

Snehasish

Hello Snehasish,

1) This mailing list focuses on Redis OSS. Redis Enterprise is a commercial product: sup...@redis.com is the best place to seek assistance, and https://docs.redis.com/latest/rs is where the docs are at. That said, configuring the enterprise edition is done via its UI/CLI/API rather than the config file IIRC.

2) Redis doesn't have a "default caching time". Each key is created without a TTL (time to live), and thus is considered as "persistent" by default. Setting a TTL for a key (e.g. with the `TTL` command) makes the key "volatile", so it expires when the TTL is reached.

Cheers,

Itamar

Hi,

You can also configure Redis as a cache.

Key eviction is not conditioned on time but on a maximum memory configured by the configuration parameter `maxmemory`.

See https://redis.io/docs/reference/eviction/ for more information.
