python - use standard datastore index or build my own -

-

i running webapp on google appengine python , app lets users post topics , respond them , website collection of these posts categorized onto different pages.

now have around 200 posts , 30 visitors day right taking 20% of reads , 10% of writes datastore. wondering if more efficient use google app engine's built in get_by_id() function retrieve posts ids or if better build own. of queries have use gql or built in query language because retrieved on more , id wanted see better.

thanks!

are doing efficient caching? (or caching @ all).

also, if you're using many writes 300 posts, seems might have problem models. have looked @ datastore viewer seem how many writes use per entity?

you might read docs on exploding indexes, maybe that's part of problem?

it's way better use get_by_id(). finds exact object, , costs way less (counts query 1 entity).

how copy observablecollection item observablecollection without reference of first collection? here observablecollection item value changes affecting both collections. code private observablecollection<ratemodel> _allmetalrate = new observablecollection<ratemodel>(); private observablecollection<ratemodel> _metalrateondate = new observablecollection<ratemodel>(); public observablecollection<ratemodel> allmetalrate { { return this._allmetalrate; } set { this._allmetalrate = value; notifypropertychanged("metalrate"); } } public observablecollection<ratemodel> metalrateondate { { return this._metalrateondate; } set { this._metalrateondate = value; notifypropertychanged("metalrateondate"); } } foreach (var item in metalrateondate) allmetalrate.add(item); what causing , how can solve it? you need clone object referenced item before it's a...

All overlapping substrings matching a java regex -

-
is there api method returns (possibly overlapping) substrings match regular expression? for example, have text string: string t = 04/31 412-555-1235; , , have pattern: pattern p = new pattern("\\d\\d+"); matches strings of 2 or more characters. the matches are: 04, 31, 412, 555, 1235. how overlapping matches? i want code return: 04, 31, 41, 412, 12, 55, 555, 55, 12, 123, 1235, 23, 235, 35. theoretically should possible -- there obvious o(n^2) algorithm enumerates , checks substrings against pattern. edit rather enumerating substrings, safer use region(int start, int end) method in matcher . checking pattern against separate, extracted substring might change result of match (e.g. if there non-capturing group or word boundary check @ start/end of pattern). edit 2 actually, it's unclear whether region() expect zero-width matches. specification vague, , experiments yield disappointing results. for example: string line = "xx90xx"; strin...
