To handle dictionary complex type, try to place this code in
ColumnPageWrapper
```
@Override public int fillSurrogateKey(int rowId, int chunkIndex, int[]
outputSurrogateKey,
KeyStructureInfo restructuringInfo) {
byte[] rowBytes = columnPage.getBytes(rowId);
outputSurrogateKey[chunkIndex] =
CarbonUtil.getSurrogateInternal(rowBytes, 0, rowBytes.length);
return chunkIndex + 1;
}
```
