Cosmos DB. I want all my data in same collection. Can I achieve this with an unlimited collection?












0















At the momment I'm using Cosmos DB fixed 10 gb where I save all my data in same collection. I want to continue this way. So do I just need to create an unlimited collection. When I do that it ask for a partion key which I don't quite understand what it is for. I have tried to read about it but didn't get much clever. Hope you guys can help me.



Today I create documents like this. Should it be done in another way if using unlimited collection. Thinking about should i declare the partion key somewhere?:



protected async Task<bool> CreateDocumentAsync(Resource document)
{
var collectionUri = UriFactory.CreateDocumentCollectionUri(_db.Options.Value.DatabaseName, _db.Options.Value.CollectionName);

ResourceResponse<Document> result = null;

for (int i = 0; i < MaxRetryCount; i++)
{
try
{
result = await _db.Client.CreateDocumentAsync(UriFactory.CreateDocumentCollectionUri(_db.Options.Value.DatabaseName, _db.Options.Value.CollectionName), document);
break;
}
catch (DocumentClientException dex) when (dex.StatusCode.HasValue && (int)dex.StatusCode.Value == 429)
{
_logger.LogWarning($"");
await Task.Delay(dex.RetryAfter);
}
}

if (result == null)
return false;

int statusCode = (int)result.StatusCode;
return statusCode >= 200 && statusCode < 300;
}

          The partition key value can be specified by providing the RequestOptions object with the PartitionKey value set.



          Your create document line would become:



          var requestOptions = new RequestOptions{
          PartitionKey = new PartitionKey("yourPartitionKeyValueHere");
          }

          result = await _db.Client.CreateDocumentAsync(UriFactory.CreateDocumentCollectionUri(_db.Options.Value.DatabaseName, _db.Options.Value.CollectionName), document, requestOptions);


          However it does should like you don't understand CosmosDB partitioning which means you can get in really deep pitfall.



          The partition key definition should be a property that most of the times if not always, is known to you when you are doing querying or reading of documents.



          I highly recommend you watch this video. It will greatly help you understand partitioning: https://azure.microsoft.com/en-us/resources/videos/azure-documentdb-elastic-scale-partitioning/



          On a side note, I can see several mistakes in the way you are using the CosmosDB SDK which I cannot fix in a single answer. For example, the CosmosDB SDK has already logic to handle the retry policy logic on the document client level via the RetryOptions object so you don't need to write any custom code. I would suggest you read more of the CosmosDB documentation.
