Subject Re: Building SSTables using SSTableSimpleUnsortedWriter (v. 1.2.3)
Date Wed, 24 Apr 2013 12:40:56 GMT
Hi David,

We have adapted Bulkload example provided by Datastax as below to write SSTables for column
family that uses Composite keys and this is working fine for us. Hope this will be of use
to you.



       List<AbstractType<?>> compositeList = new ArrayList<AbstractType<?>>();

        compositeList.add(UTF8Type.instance);

        compositeList.add(UTF8Type.instance);

        compositeList.add(UTF8Type.instance);






        SSTableSimpleUnsortedWriter usersWriter = new

SSTableSimpleUnsortedWriter(

                directory,

                new Murmur3Partitioner(),

                keyspace,

                columnFamily,

                CompositeType.getInstance(compositeList),

                null,

                64);


        String line;

        int lineNumber = 1;

        CsvEntry entry = new CsvEntry();

        long timestamp = System.currentTimeMillis() * 1000;

        while ((line = reader.readLine()) != null)

        {

            if (entry.parse(line, lineNumber))

            {

                CompositeType.Builder builder = new CompositeType.Builder(CompositeType.getInstance(compositeList)
);

                usersWriter.newRow(bytes(entry.Key));

                builder.add(bytes(entry.column1));

                builder.add(bytes(entry.column2));

                builder.add(bytes(entry.column3));

                usersWriter.addColumn(builder.build(), (bytes(entry.column4)),timestamp);

             }

            lineNumber++;

        }
