Any update on this?

 I believe my "uncategorized pages" tool at http://tools.wmflabs.org/superyetkin/kategorisizsayfalar.php is showing cached results.

 Yetkin,

I am not sure what the answer here is but I believe to get further with this issue specifics are needed.  What queries? When are they run? What do you hope to get back that you are not?  Which wiki databases are you querying? Can you show examples of specific inconsistent results?

 Hello Jamie,
Is there any other caching mechanism on labs replicas? For the past few days, I see my tools are showing results that I believe did not appear before. How can we make sure the queries run on replica servers return consistent results?

 Hi, Yetkin,

If you mean query cache on the labs replica servers or the tools-db one, it is disabled by default on all servers:

```
$ mysql  -e "SHOW GLOBAL VARIABLES like '%query_cache%'"
+----------------------------- -+---------+
| Variable_name                | Value   |
+----------------------------- -+---------+
| query_cache_size             | 0       |
| query_cache_type             | OFF     |
+----------------------------- -+---------+
```

Hello,
Is there any way to eliminate caching on Tool Labs? SQL_NO_CACHE option in MySQL does not seem to work at all.
Thanks.
