Elasticsearch Insert single key if not exists, without affecting other keys -


in of documents, have key present school. document is:

{     "id" : "123",     "name" : "robert",     "school" : "public" }

now, school not present in documents. want insert school key in documents not present default string.

i using elasticsearch version number 2.4.5. how can it? looking @ bulk update?

i use update query api this. can search documents don't have school field , set whatever default value wish:

post your-index/your-type/_update_by_query {   "query": {     "bool": {       "must_not": {         "exists": {           "field": "school"         }       }     }   },   "script": {     "inline": "ctx._source.school = 'dummy'"   } }

note need enable dynamic scripting , restart es server.

recursion - Can every recursive algorithm be improved with dynamic programming? -

i first year undergraduate csc student looking competitive programming. recursion involves defining , solving sub problems. understand, top down dynamic programming (dp) involves memoizing solutions sub problems reduce time complexity of algorithm. can top down dp used improve efficiency of every recursive algorithm overlapping sub problems? dp fail work , how can identify this? the short answer is: yes. however, there constraints. obvious 1 recursive calls must overlap. i.e. during execution of algorithm, recursive function must called multiple times same parameters. lets truncate recursion tree memoization. can use memoization reduce number of calls. however, reduction of calls comes price. need store results somewhere. next obvious constraint need have enough memory. comes not-so obvious constraint. memory access requires time. first need find result stored , maybe copy location. in cases, might faster let recursion calculate result instead of loading somewher...
