Apologies, "Google Groups" resized. I did not notice till you mentioned.
The image is 1.7 mg and it was 1400 pixels wide. I cropped it, hope this
time it will be more visible.

the tag of the message: python27, I thought people used that for "saying
the language", I guess not easy to read. I am using ndb, as db is
deprecated.
Removing some if-then-else, the code is like this:
query = TATripDB.query( TATripDB.draft == 0 )
if request.offset:
cursor = Cursor( urlsafe = request.offset )
else:
cursor = None
# limit = request.limit
rows, next_cursor, more = query.fetch_page( 200, start_cursor =
cursor )
ret = [ ]
com_cache = { }
cur_cache = { }
if rows:
unique_temporal_user = self.get_ta_profile( rows[ 0
].from_agency )
for r in rows:
ret.append( get_tatrip_answer( unique_temporal_user
# user_set[ r.key.parent(
).id( ) ]
, r
, vlc_of_trip_key(
userID_key, r.key )
, cur_cache
, com_cache ) )
return ExploreTATripA( trips = ret
, next_token = next_token
, cur_rates = cur_rates )
The version of the memcache introduce some changes:
tatrips_keys = memcache.get( 'TATRIPS_KEYS' )
if tatrips_keys:
rows = map( lambda x: self.get_tatrip_from_key( x
), tatrips_keys )
I thought of using this method to avoid putting big object in memcache.
This is maybe what you refer as getting in larger batch size? Later I am
going to do some more experiments. Thank you for the suggestion!
