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 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?
