rds-json generate json with index key on first level of array

[Mauro Stettler]

Hello Nginx list

I'm using OpenResty with libdrizzle to provide a faster API to query
certain things from my db.

My current config is like this:

        location ~* ^/resty/usersTable/userId/([0-9\,]+)$  {
            set_unescape_uri $uid $1;
            drizzle_query 'select  id, nickname, age, age_p, city, plz,
wio_plz, gender from users where id in ($uid)';
            drizzle_pass projectdb;
            rds_json on;
        }

So this works fine and it gives me the expected output.

My problem is that if I query many user IDs i'm only getting a flat array
of arrays without index key. But to improve the processing speed on the
client side, I would like to define that the 'id' field should be the first
level index in the returned array. I am trying to show what I mean:

Current output:

[

{"id":1971,"nickname":"Robby1","age":28,"age_p":42,"city":"Dresden","plz":"","wio_plz":"2,4,5","gender":"m"},

{"id":1972,"nickname":"Robby2","age":29,"age_p":43,"city":"Dresden2","plz":"","wio_plz":"4,5","gender":"f"},

{"id":1973,"nickname":"Robby3","age":30,"age_p":44,"city":"Dresden3","plz":"","wio_plz":"5","gender":"m"},
]

What I want:

[

1971:{"nickname":"Robby1","age":28,"age_p":42,"city":"Dresden","plz":"","wio_plz":"2,4,5","gender":"m"},

1972:{"nickname":"Robby2","age":29,"age_p":43,"city":"Dresden2","plz":"","wio_plz":"4,5","gender":"f"},

1973:{"nickname":"Robby3","age":30,"age_p":44,"city":"Dresden3","plz":"","wio_plz":"5","gender":"m"},
]

Is there some way how I can define a first level index key in rds-json? I
already checked the `rds_json_root` parameter, but this doesn't seem to be
what I'm looking for.

Thanks,

Mauro
