ElasticSearch: Updating nested document in array -


given document

curl -xput 'localhost:9200/test/me/here' -d '{   "top" : [     { "searchkey" : "change"},     { "searchkey" : "keep"}   ] }'

i need update query add new field sub-document searchkey equal change , keep other sub-document intact. expected result then:

{   "top" : [     { "searchkey" : "change", "newfield" : "newvalue"},     { "searchkey" : "keep"}   ] }

running query selects inner document index works, not know inner order in advance , quite fragile anyways:

curl -xpost 'localhost:9200/test/me/here/_update' -d '{     "script" : "ctx._source.top[0].newfield = v",     "params" : {       "v" : "newvalue"     } }'

is there way tell es add new field inner document matches condition? like:

curl -xpost 'localhost:9200/test/me/here/_update' -d '{     "script" : "ctx._source.top[ctx._source.top.searchkey == s].newfield = v",     "params" : {       "s" : "change",       "v" : "newvalue"     } }'

or, better , save headache if eliminate array , transform document to:

{ "change" : {}, "keep" : {} }

you can use update script. see example:

put test/data/3/ {    "source": [      {        "name": "a",        "count": 1      },      {        "name": "b",        "count": 2      },      {        "name": "c",        "count": 3      }    ] }  test/data/3  post test/data/3/_update {  "script": " (int = 0; < source.size(); i++) {boolean f = false;for (int j = 0; j < ctx._source.source.size(); j++) {if (ctx._source.source[j].name == source[i].name) {ctx._source.source[j].count = source[i].count;f=true;break;}}\nif(!f){ctx._source.source.add(source[i]);}}",  "params": {    "source": [      {        "name": "a",        "count": 10      },      {        "name": "b",        "count": 30      },      {        "name": "d",        "count": 50      }    ]  } }  test/data/3

python - Django-cities exits with "killed" -

i trying install django-cities on server 500mb ram. whenever run: manage.py cities the system exits saying killed. trying run: manage.py cities --import=country --force worked, guessing matter of running out of memory. to bypass, tried refer package local copy of cities' data file. still didn't work. any ideas on how can migrate data without having increase memory on server? based on suggestion comments, solved setting temporary swap file. if unfamiliar it, can follow these steps: set swap file touch /var/swap.img chmod 600 /var/swap.img set swap file size cd /var dd if=/dev/zero of=/var/swap.img bs=1024k count=1000 this create 1gb swap file. prepare disk image mkswap /var/swap.img activate swap memory swapon /var/swap.img once done, can turn off swap image: swapoff /var/swap.img more information on virtual memory , swap files can found here: https://www.digitalocean.com/community/tutorials/how-to-configure-virtual-me...
