.net - Storing JSON object in CASSANDRA -



.net - Storing JSON object in CASSANDRA -

i want store json in cassandra db. each fields of json should mapped respective column.

is possible ? if possible how can accomplish it?.

please help me guys..

the reply same given in other post - cassandra no more schema-less there no out-of-the-box solution (unless have pre-defined json structure). create first-level json construction map<text, text> (if, think, need select entry key)

{ "keya": { "keyb": 5, "keyc": "somestring" }, "keyd": 3; }

this mapped next map entries

<keya, '{ "keyb": 5, "keyc": "somestring" }'> <keyd, '3'>

in way can content first-level key in json have search subsequent entries. "flatten" keys map this:

<keya, '{ "keyb": 5, "keyc": "somestring" }'> <keya.keyb, '5'> <keya.keyc": ' "somestring" '> <keyd, '3'>

you might want insert custom entry in map store original json. in way should able search entry map much bigger original json since it's denormalized perform key based searches. more: since maps statically typed have map integers, uuid, float or whatever strings.
