Unable to query using only the rangeKey.

[Shishir Anshuman]

I just started working on DynamoDB so please forgive me if the following seems silly.

• I have a model with a hashKey and a rangeKey. Let's name these as HASH and RANGE respectively.
• A global secondary index: GlobalIndex is added to the model as well.

Now what I want is to get the list of records by rangeKey. I don't want to use the scan operation since it impacts the performance. I am unable to achieve this with the query operation.
Trying to achieve something like this with dynogels.

Any kind of help would be really helpful to me.

Thanks.

Dynogels: 9.0.0
Node: 6.10.3

You cannot query on only the range key. Does your global secondary index use your table's range key as its hash key? Showing your model would be helpful.

Sure. Here is the model I am using:

dynogels.define('user-address', {
    hashKey : 'user_id',
    rangeKey: 'location',

    timestamps : true,

    schema : {
        location: Joi.string(),
        pin: Joi.number(),
        user_id: Joi.string()
    },

    indexes: [{
        hashKey: 'user_id',
        rangeKey: 'location',
        name: 'AddressGlobalIndex',
        type: 'global',
    }],
});

After reading your comment, I think I understand what I am doing wrong. Will let you know

Your index has the same hash key and range key as your table. This is entirely redundant.

Yes, you are right. Fixed it. It was a dumb mistake. Thanx a lot for the help. ✌️
