Looking at our git history, we **did** previously have `RESULTS_BACKEND` set
to a dict, which
would have caused exactly the error you're describing:
```python
# Previous configuration (from git history):
RESULTS_BACKEND = {
'cache_type': 'redis',
'cache_redis_host': REDIS_HOST,
'cache_redis_port': REDIS_PORT,
'cache_redis_db': REDIS_DB,
}
We fixed this by changing to the proper cachelib object:
# Current configuration:
from cachelib.redis import RedisCache
RESULTS_BACKEND = RedisCache(
host=REDIS_HOST,
port=int(REDIS_PORT),
db=int(REDIS_DB),
key_prefix='superset_results_'
)
So yes, we likely encountered the "'dict' object has no attribute 'set'"
error during development and fixed it by switching from the dict
configuration to the proper RedisCache object.
