Cacheops not working in Production.
Cacheops is not working for me in production but it does in development . I can't tell if it's my settings. Here is my settings. `CACHEOPS_DEGRADE_ON_FAILURE=True CACHEOPS_ENABLED = True CACHEOPS_REDIS = { 'host': 'localhost', 'port': 6379,
} CACHEOPS_DEFAULTS = { 'timeout': 60*60 } CACHEOPS = {
'libman.*': {'ops':'all'},
}`
How do you know it is not working?
Through DjDT. The no of queries are the same the first time I access a page and after I refresh...
There could be many reasons:
- Fail to connect to redis, see logs, there might be warnings. Because of
CACHEOPS_DEGRADE_ON_FAILURE = Trueyou still continue. - Queries are not the same, this is common if timestamp or some random component is involved.
- Cache got invalidated.
- Queries are not being cached because of transactions. Any transaction once performed any write query starts bypassing cache to be safe.
Aside from looking into logs you may try redis-cli monitor to see whether cache is being saved and or deleted. Or you may use signals cacheops provides to log something, see README.
