Examples with CounterColumn org.apache.cassandra.db.CounterColumn used on opensource projects

Example 1 with CounterColumn

use of org.apache.cassandra.db.CounterColumn in project eiger by wlloyd.

the class SSTableExportTest method testExportCounterCf.

@Test
public void testExportCounterCf() throws IOException {
    File tempSS = tempSSTableFile("Keyspace1", "Counter1");
    ColumnFamily cfamily = ColumnFamily.create("Keyspace1", "Counter1");
    SSTableWriter writer = new SSTableWriter(tempSS.getPath(), 2);
    // Add rowA
    cfamily.addColumn(null, new CounterColumn(ByteBufferUtil.bytes("colA"), 42, System.currentTimeMillis()));
    writer.append(Util.dk("rowA"), cfamily);
    cfamily.clear();
    SSTableReader reader = writer.closeAndOpenReader();
    // Export to JSON and verify
    File tempJson = File.createTempFile("Counter1", ".json");
    SSTableExport.export(reader, new PrintStream(tempJson.getPath()), new String[0]);
    JSONObject json = (JSONObject) JSONValue.parse(new FileReader(tempJson));
    JSONArray rowA = (JSONArray) json.get(asHex("rowA"));
    JSONArray colA = (JSONArray) rowA.get(0);
    assert hexToBytes((String) colA.get(0)).equals(ByteBufferUtil.bytes("colA"));
    assert ((String) colA.get(3)).equals("c");
    assert (Long) colA.get(4) == Long.MIN_VALUE;
}

Example 2 with CounterColumn

use of org.apache.cassandra.db.CounterColumn in project eiger by wlloyd.

the class SSTableImportTest method testImportCounterCf.

@Test
public void testImportCounterCf() throws IOException, URISyntaxException {
    // Import JSON to temp SSTable file
    String jsonUrl = resourcePath("CounterCF.json");
    File tempSS = tempSSTableFile("Keyspace1", "Counter1");
    SSTableImport.importJson(jsonUrl, "Keyspace1", "Counter1", tempSS.getPath());
    // Verify results
    SSTableReader reader = SSTableReader.open(Descriptor.fromFilename(tempSS.getPath()));
    QueryFilter qf = QueryFilter.getIdentityFilter(Util.dk("rowA"), new QueryPath("Counter1"));
    IColumnIterator iter = qf.getSSTableColumnIterator(reader);
    ColumnFamily cf = iter.getColumnFamily();
    while (iter.hasNext()) cf.addColumn(iter.next());
    IColumn c = cf.getColumn(ByteBufferUtil.bytes("colAA"));
    assert c instanceof CounterColumn : c;
    assert ((CounterColumn) c).total() == 42;
