Jonathan Ellis resolved CASSANDRA-2210.
---------------------------------------
Resolution: Invalid
There's something wrong with your client code. But fundamentally you should
not be using raw Thrift, you should be using a client like Hector:

> butch_mutate (java) does overwrite instead of updating

> Key: CASSANDRA-2210
> URL: https://issues.apache.org/jira/browse/CASSANDRA-2210
> Project: Cassandra
> Issue Type: Bug
> Components: API
> Affects Versions: 0.7.2
> Reporter: Markus Wiesenbacher

> I want to insert a supercolumn, and I don´t know what I could use instead of
> batch_mutate. I am using this method:
> [CODE]
> client.set_keyspace(keyspace);
> List<Column> columns = new ArrayList<Column>();
> for (String key : values.keySet())
> columns.add(new Column(ByteBuffer.wrap(key.getBytes()),
> ByteBuffer.wrap(values.get(key).getBytes()), System.currentTimeMillis()));
> SuperColumn superColumn = new
> SuperColumn(ByteBuffer.wrap(name_SuperColumn.getBytes("UTF-8")), columns);
> ColumnOrSuperColumn columnOrSuperColumn = new
> ColumnOrSuperColumn();
> columnOrSuperColumn.setSuper_column(superColumn);
>
> Mutation mutation = new Mutation();
> mutation.setColumn_or_supercolumn(columnOrSuperColumn);
>
> // map<rowkey : string, map<column_family : string,
> list<Mutation>>>
> // To be more specific, the outer map key is a row key, the
> inner map key is the column family name.
> Map<ByteBuffer, Map<String, List<Mutation>>> muts = new
> HashMap<ByteBuffer, Map<String,List<Mutation>>>();
> Map<String, List<Mutation>> mut = new HashMap<String,
> List<Mutation>>();
> List<Mutation> mu = new ArrayList<Mutation>();
> mu.add(mutation);
> mut.put(column_family, mu);
> muts.put(ByteBuffer.wrap(rowKey.getBytes()), mut);
>
> client.batch_mutate(muts, ConsistencyLevel.ONE);
> [/CODE]
> I am calling the method with this:
> f.insertSuper("TEST", "super", "testrow1", "id#1", values);
> f.insertSuper("TEST", "super", "testrow1", "id#2", values);
> TEST = keyspace
> super = column family
> testrow1 = row key
> id#1 = super column key
> values = Map of key value pairs
> I would expect two entries, one with id#1 and one with id#2, but there´s only
> id#2? Is this a bug or do I have to select all columns and have to rewrite it
> again? I hope not ... ;)
> Best regards
> wiesi :)
