Hello
I'am trying to build application on GAE which use MongoDB hosted at
Mongolab provider.
Connection work, if I made new connection every request, but if I want to
reuse once established connection, GAE freeze and die on timeout.
I believe that exist some simple way, how to do that such simple task.
----- This is woring, but open new connection every request: ------
def get_database_connection():
client = pymongo.MongoClient(MONGO_URI)
DBCONN = client.get_default_database()
return DBCONN
DBCON = get_database_connection()
... do something usefull with DBCONN ...
... not store connection anywhere ....
... end request ....
---- This freeze GAE and die on timeout ---
def get_database_connection():
if "DBCONN" in globals(): # look for open connection in
instance memory
return globals()["DBCONN"]
client = pymongo.MongoClient(MONGO_URI)
DBCONN = client.get_default_database()
globals()["DBCONN"] = DBCONN # store connection to instance memory
return DBCONN
DBCONN = get_database_connection()
... do something usefull with DBCONN ...
... end request ....
--------
Probably GAE module with backend thread can be uset to keep connection open
in separate thread, but after many hours I can´t find working solution.
Hope somebody can experience with this usecase and can help me. Also link
to well-tried solution will be helpfull.
Have a nice day.
