Connection

Connection is basic configuration object. Just initialize it simply like that:

var connection = new Connection(endpoint, authorizationKey, database, collection);

Some things keep in mind:

• if Windows OS is detected, connection mode Direct and connection protocol Tcp is being used, otherwise we ended up with Gateway mode since Direct one doesn't work on OSX/Linux
• default JSON ser/deser settings are being set:

Formatting = Formatting.None,
TypeNameHandling = TypeNameHandling.None,
ContractResolver = new CamelCasePropertyNamesContractResolver()

• if you don't specify ConnectionPolicy some ultra safe retry policy settings are being used

MaxRetryAttemptsOnThrottledRequests = 1000,
MaxRetryWaitTimeInSeconds = 60

Methods

DocumentCollection CreateCollection()

Create collection if it doesn't exists.

bool DeleteCollection()

Delete collection.

Repository

Generic and non-generic repositories are available.

Easiest way is using non-generic repository like that:

var repo = new Repository(connection);

repo.Create(new { Movie = "Donkey Kong Jr.", Rating = 3 });
repo.Create(new { Movie = "King Kong", Rating = 2 });
repo.Create(new { Movie = "Donkey Kong", Rating = 1 });

var games = repo.GetList("select * from c where c.rating = @rating", new { rating = 3 });

In most cases you'd like to use POCOs like that:

const string _entity = "robot";

[EntityType("entity", _entity)]
public class Robot
{
 public string Id { get; set; }            
 public string Name { get; set; }
 public int ArtificialIq { get; set; }
 public Stamp Created { get; set; } = new Stamp();
 public bool IsOperational { get; set; }
}

We have a special attribute [Entity] useful for setting document type property. It's optional of course. If you use this attribute condition is automatically injected in "where" phrase in SQL.

var repo = new Repository<Robot>(connection);
var robot = repo.GetFirstOrDefault(); // generated sql "select top 1 * from c where c.entity = 'robot'
var robots = repo.GetList("select * from c where c.entity = @entity and c.artificialIq > @iq",
new
{
    entity = _entity,
    iq = 120
});

Methods for repository

T GetFirstOrDefault(SqlQuerySpec query, FeedOptions feedOptions = null)

T GetFirstOrDefault(DynamicQuery query, FeedOptions feedOptions = null)

T GetFirstOrDefault(string sql, object parameters, FeedOptions feedOptions = null)

T GetFirstOrDefault(string id, FeedOptions feedOptions = null)

Get first document found or null. Three types of queries, direct Id of the document or just null (in this case EntityType is auto included).

T Upsert(T entity, RequestOptions requestOptions = null)

Upsert document.

T Create(T entity, RequestOptions requestOptions = null)

Create document.

T Replace(T entity, RequestOptions requestOptions = null)

Replace document.

bool Delete(string id, RequestOptions requestOptions = null)

bool Delete(T entity, RequestOptions requestOptions = null)

Delete document.

IList<T> GetAll(FeedOption feedOptions = null)

Get all documents (in this case EntityType is auto included).

IList<T> GetList(SqlQuerySpec query, FeedOptions feedOptions = null)

IList<T> GetList(DynamicQuery query, FeedOptions feedOptions = null)

IList<T> GetList(string query, object parameters = null, FeedOptions feedOptions = null)

Get list of documents.

Aggregate repository

Helper repository for aggregate calls. It automagically handles possibility of partial results.

var agr = new AggregateRepository(connection);
var einstein = repo.Get("select max(c.iq) from c where c.gender", new { gender = "M" });

Methods for aggregate repository

long? Get(SqlQuerySpec query, FeedOptions feedOptions = null)

long? Get(DynamicQuery query, FeedOptions feedOptions = null)

long? Get(string sql, object parameters, FeedOptions feedOptions = null)

Get a numeric result of aggregate function.

Tokens

Since it's kinda complicated to filter stamps (datetimes) directly through SQL queries. We have two timestamp objects:

SimpleStamp

var created = new SimpleStamp(dateTime);

In JSON:

"created": {
 "dateTime": "2017-03-29T15:58:50.8828571+02:00",
 "epoch": 1490803130
}

Stamp

var created = new Stamp(dateTime);

In JSON:

"created": {
 "dateTime": "2016-09-13T20:06:22.3214018+02:00",
 "epoch": 1473797182,
 "year": 2016,
 "month": 9,
 "day": 13,
 "hour": 20,
 "minute": 6,
 "second": 22
}

Stamps are automatically compared by epoch:

var q = new DynamicQuery("select * from c where c.epoch = @stamp or c.epoch2 = @stamp2", 
new
{
    stamp = new Stamp(new DateTime(2000, 1, 1)),
    stamp2 = new SimpleStamp(new DateTime(2001, 1, 1))
});

results in:

select * from c where c.epoch = 946684800 or c.epoch2 = 9466848002

Queries

DynamicQuery

More comfort way:

var ids = new List<int> { 4, 5, 2 };
var q = new DynamicQuery("select * from c where c.items in @ids", new { ids });            

results in:

select * from c where c.items in (4,5,2)

SqlQuerySpec

var q = new SqlQuerySpec ( "select * from c where c.entity = @entity", new SqlParameterCollection { new SqlParameter("@entity", "robot"), } );

results in:

select * from c where c.entity = 'robot'

PureString

Of course.

LINQ

Not at the moment. I don't like it very much. I'm gonna implement it maybe in the future.
