索引字段不够(需要复合索引)
11 |
xx/models.py 143-146行
12 | statuses = list(coll.find(
13 | {"is_update": False},
14 | {"uid": 1}
15 | ).sort('date', -1).limit(200))
16 |
17 | > db.status_5008fe57b3158aa4709ecd8f_201311.getIndexes()
18 | [
19 | {
20 | "v" : 1,
21 | "key" : {
22 | "_id" : 1
23 | },
24 | "ns" : "dongwm.status_5008fe57b3158aa4709ecd8f_201311",
25 | "name" : "_id_"
26 | },
27 | {
28 | "v" : 1,
29 | "key" : {
30 | "date" : -1
31 | },

34 | },
35 | {
36 | "v" : 1,
37 | "key" : {
38 | "idate" : -1
39 | },
40 | "ns" : "dongwm.status_5008fe57b3158aa4709ecd8f_201311",
41 | "name" : "idate_-1"
42 | }
43 | ]
44 |
45 |
46 | db["status_5008fe57b3158aa4709ecd8f_201311"].ensureIndex({"is_update": 1, "date": 1}, {"background": true})

没有索引
49 |
xx/tasks.py 551-564行
50 | pre_date = update_date - timedelta(hours=1)
51 | pre_infcoll = s_db["inf_%s_%s" % (
52 | key["_id"], pre_date.strftime("%Y%m")

59 | minute=0,
60 | second=0,
61 | microsecond=0

索引顺序问题
74 |
xx/models.py 1110-1119行
