Review Comment:
Its better to use Class instead of String to handle cases in which certain
classes moved to different package.
```suggestion
Class<?> keyType = dbColumnFamilyDefinition.getKeyType();
if (keyType.equals(String.class)) {
return startKey.getBytes();
} else if (keyType.equals(ContainerID.class)) {
return new ContainerID(Long.parseLong(startKey)).getBytes();
} else if (keyType.equals(Long.class)) {
return Longs.toByteArray(Long.parseLong(startKey));
} else if (keyType.equals(PipelineID.class)) {
return PipelineID.valueOf(UUID.fromString(startKey)).getProtobuf()
.toByteArray();
```
