Failed to Create document in to azure Cosmos-db using Azure Android SDK

Question

I am using azure android SDK for adding new records into collection items. We don't have partition keys for our cosmos-DB. so I am passing as null for it.

it will give me the below error

partition key supplied in x-ms-partitionkey header has fewer components than defined in the collection.

Can anyone help me to come out of this?

Answer 1

You need to mark the property you're using as the partition key with the @PartitionKey annotation, e.g.:

@PartitionKey
    var testKey = ""

in C#, we use Undefined.Value and everything will be fine.

client.DeleteDocumentAsync(
          UriFactory.CreateDocumentUri(DbName, CollectionName, id), 
          new RequestOptions() { PartitionKey = new PartitionKey(Undefined.Value) });

Answer 2

The azure android SDK required partition key, it not accepting null or empty. Also if you have a bunch of records to store in the cosmos DB, then you must use the partition key other you may face the partition key limit reached the issue in the future. Azure provides a max of 10 GB for a logical partition.

I have created a new collection with the user wise partition and pass the partition key value eg. patitionKey=/.UserID in my object. this will work for me. Also managing partition key limit issue.

so it will be good to use the partition key in advance to avoid the problem in the future.
