Operations: Counters: How to Get Counters

Get Single Counter

public GetCountersOperation(string docId, string counter, bool returnFullResults = false)

Get Multiple Counters

public GetCountersOperation(string docId, string[] counters, bool returnFullResults = false)

Get All Counters of a Document

public GetCountersOperation(string docId, bool returnFullResults = false)

The operation returns a CountersDetail object, which holds a list of CounterDetail objects

public class CountersDetail
{
    public List<CounterDetail> Counters;
}

public class CounterDetail
{
    public string DocumentId; // ID of the document that holds the counter
    public string CounterName; // The counter name
    public long TotalValue; // Total counter value
    public Dictionary<string, long> CounterValues; // A dictionary of counter values per database node
    public long Etag; // Counter Etag
    public string ChangeVector; // Change vector of the counter
}

Assume we have a document "users/1" which holds 3 counters -
"likes", "dislikes" and "downloads" - with values 10, 20 and 30 (respectively)

Example #1 : Get single counter

var operationResult = store.Operations
    .Send(new GetCountersOperation("users/1", "likes"));

Result:

{
	"Counters": 
    [
		{
			"DocumentId" : "users/1",
			"CounterName" : "likes",
			"TotalValue" : 10,
			"CounterValues" : null
		}
	]
}

Example #2 : Get multiple counters

var operationResult = store.Operations
    .Send(new GetCountersOperation("users/1", new []{"likes", "dislikes" }));

Result:

{
	"Counters": 
    [
		{
			"DocumentId" : "users/1",
			"CounterName" : "likes",
			"TotalValue" : 10,
			"CounterValues" : null
		},
        {
			"DocumentId" : "users/1",
			"CounterName" : "dislikes",
			"TotalValue" : 20,
			"CounterValues" : null
		}
	]
}

Example #3 : Get all counters

var operationResult = store.Operations
    .Send(new GetCountersOperation("users/1"));

Result:

{
	"Counters": 
    [
		{
			"DocumentId" : "users/1",
			"CounterName" : "likes",
			"TotalValue" : 10,
			"CounterValues" : null
		},
        {
			"DocumentId" : "users/1",
			"CounterName" : "dislikes",
			"TotalValue" : 20,
			"CounterValues" : null
		},
        {
			"DocumentId" : "users/1",
			"CounterName" : "downloads",
			"TotalValue" : 30,
			"CounterValues" : null
		}
	]
}

Example #4 : Include full values in the result

var operationResult = store.Operations
    .Send(new GetCountersOperation("users/1", "likes", true));

Result:

{
	"Counters": 
    [
		{
			"DocumentId" : "users/1",
			"CounterName" : "likes",
			"TotalValue" : 10,
			"CounterValues" : 
            {
                "A:35-UuCp420vs0u+URADcGVURA" : 5,
                "B:83-SeCFU29daUOxfjUcAlLiJw" : 3,
                "C:27-7i7GP8bOOkGYLNflO/rSeg" : 2,
            }
		}
	]
}
