i new couchdb , trying pull data couchdb incrementally. sequence number source me. added

"options": {    "local_seq": true }, 

in design document. proper usage of 'options' field in design document? want see local_seq field result.

thanks

according documentation, need define option on design document. once it's defined, can use _local_sec document property. have defined in mapping function, emit keys value of _local_sec.

have try :

{   "_id": "_design/global",   "language": "javascript",   "views": {     "byage": {       "map": "function(doc){if(doc.age)emit(doc._id,doc._local_sec);}"     }   },  "options": {             "local_seq": true           } }
