Jonathan Ellis commented on CASSANDRA-1578:
-------------------------------------------
you can annotate specific columns with metadata specifying what type of data
should be allowed, and optionally declaring an index on it (see
CASSANDRA-1583). if we know that a column value is LongType, we should convert
the byte[] into a Long before displaying, and vice versa for accepting input.
Right now we are just assuming all values are Strings:
{code}
// print results
css_.out.printf("=> (column=%s, value=%s, timestamp=%d)\n",
formatColumnName(keySpace, columnFamily, column), new
String(column.value, "UTF-8"), column.timestamp);
{code}
{code}
// do the insert
thriftClient_.insert(key.getBytes(), new
ColumnParent(columnFamily).setSuper_column(superColumnName),
new Column(columnNameAsByteArray(columnName,
columnFamily), value.getBytes(), FBUtilities.timestampMicros()),
ConsistencyLevel.ONE);
{code}
