Update/append redis values

I have recently started using redis. Currently it's simple key value storage. For example:

$this->redis->set('GET_ALL_DEVICES', json_encode($data));

Now if there is new entry into device table, I want to append new entry into same cached data I have. Don't want to flush cached object and create new one to reflect new entry. Is there any way to do this in redis?

There is no table in Redis. You must learn what Redis specific data types are.

In this case, a SET could be the right structure to be used, if you don't need the data to be ordered. So you should perform a SADD (adds a value to SET) instead of a SET instruction, which sets the value for a single string.

$this->redis->sadd('GET_ALL_DEVICES', json_encode($data));

According to your use case, a LIST or a SORTED set may be more appropriate than a SET to store your data.
