> Hello all,
> Please forgive me, if the issue I am describing is not a bug, but rather my
> lack of knowledge. I have just started playing with Cassandra and at this
> moment I am stuck.
> I am a .NET developer and have very little experience with Java. This is why
> I decided to use Thrift generated C# classes in order to communicate with
> Cassandra. It appears I can insert columns, but I cannot updated them using
> C# interface. At the same time I can do it successfully using cassandra-cli.
> Let me provide some details:
> // Inserting column:
> long tStamp = DateTime.Now.Millisecond;
> //Insert the data into the column 'name'
> client.insert("Keyspace1",
> "Test",
> nameColumnPath,
> utf8Encoding.GetBytes("Value"),
> tStamp,
> ConsistencyLevel.ONE);
> ColumnOrSuperColumn returnedCol = new ColumnOrSuperColumn();
> returnedCol = client.get("Keyspace1", "Test", nameColumnPath,
> ConsistencyLevel.ONE);
> Console.WriteLine("Column Data in Keyspace1/Standard1: name: {0},
> value: {1}",
> utf8Encoding.GetString(returnedCol.Column.Name),
>
> utf8Encoding.GetString(returnedCol.Column.Value));
> // Column Data in Keyspace1/Standard1: name: name, value: Value
> // update same column:
> Console.WriteLine("Update column value");
> //Insert the data into the column 'name'
> client.insert("Keyspace1",
> "Test",
> nameColumnPath,
> utf8Encoding.GetBytes("Value updated"),
> tStamp,
> ConsistencyLevel.ONE);
> returnedCol = client.get("Keyspace1", "Test", nameColumnPath,
> ConsistencyLevel.ONE);
> Console.WriteLine("Column Data in Keyspace1/Standard1: name: {0},
> value: {1}",
> utf8Encoding.GetString(returnedCol.Column.Name),
>
> utf8Encoding.GetString(returnedCol.Column.Value));
> //Column Data in Keyspace1/Standard1: name: name, value: Value (it has NOT
> been changed!!!)
> Now I try achieve same results with cassandra-cli:
> cassandra> set Keyspace1.Standard1['Test']['name']='Value'
> Value inserted.
> cassandra> get Keyspace1.Standard1['Test']
> => (column=6e616d65, value=Value, timestamp=1272932956231000)
> Returned 1 results.
> cassandra> set Keyspace1.Standard1['Test']['name']='Value updated'
> Value inserted.
> cassandra> get Keyspace1.Standard1['Test']
> => (column=6e616d65, value=Value updated, timestamp=1272932970637000)
> Returned 1 results.
> cassandra>
> As you can see it works.
> It doesn't matter if timestamps values are different for C# example. I tried
> it too.
> Thank you very much.
