I'm running MongoDB on Windows. I have 1 or more threads that drop and recreate a collection.
Using mongo.exe with the show collections() command, I'm seeing multiple collections with the same name (well over 1,000 collections with the same name!).
When I run validate:
> db.MY_COLLECTION.validate()
I get:
{ "errmsg" : "ns not found", "ok" : 0, "valid" : false }
The size() command returns 0, and find() returns nothing.
My question is: Is MongoDB thread safe? A follow on question would be something like 'Am I doing this correctly (dropping and recreating) or is there a better way to refresh the whole content of a collection?'
