usersWriter.addColumn(compositeType.decompose("firstname"),

compositeType.decompose(bytes(entry.firstname)),
timestamp);
usersWriter.addColumn(compositeType.decompose("lastname"),
compositeType.decompose(bytes(entry.lastname)),
timestamp);

usersWriter.addColumn(compositeType.decompose("password"),
compositeType.decompose(bytes(entry.password)),
timestamp);

usersWriter.addColumn(compositeType.decompose("age"),
numericType.decompose(bytes(entry.age)),timestamp);

usersWriter.addColumn(compositeType.decompose("email"),
compositeType.decompose(bytes(entry.email)),timestamp);

9. Now, to assign the addresses collection, we need to construct and

assign with data type as Set :

SetType<String> addressType =
newSetType<String>(UTF8Type.instance);

// column name
ByteBuffer byteBuffer1 =
compositeType.decompose("addresses");

// set value
ByteBuffer byteBuffer2 =
compositeType.decompose("noida");

10. We need to create a bytebuffer instance and add a column:

ByteBuffer bb =
ByteBuffer.allocate(byteBuffer2.capacity()+byteBuffer1.capacity());
bb.put(byteBuffer1);
bb.put(byteBuffer2);
bb.flip();
