Jonathan Ellis reopened CASSANDRA-1048: --------------------------------------- > A column value is not updated via Thrift 0.2.0 API (C#) > -------------------------------------------------------- > > Key: CASSANDRA-1048 > URL: https://issues.apache.org/jira/browse/CASSANDRA-1048 > Project: Cassandra > Issue Type: Bug > Components: Tools > Affects Versions: 0.6.1 > Environment: Windows Server 2003 R2 32-bit, JRE 6, Cassandra 0.6.1, > Thrift 0.2.0, MS VS 2008/.NET 3.5 > Reporter: Alexander S > Attachments: storage-conf.xml > > > 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. -- This message is automatically generated by JIRA. - You can reply to this email to add a comment to the issue online.
