I found the solution, here it is if someone needs it:
CellNameType cellComparator = columnFamily.getComparator();
int clusteringPrefixSize = cellComparator.clusteringPrefixSize();
for (int prefixNb = 0; prefixNb < clusteringPrefixSize; prefixNb++) {
AbstractType<?> subtype = cellComparator.subtype(prefixNb);
ByteBuffer clusteringKeyBytes = cell.name().get(prefixNb);
String value = subtype.getString(clusteringKeyBytes);
...
}

Subject: Retrieving clustering columns values from cell names
Hi Cassandra developers,
I'm implementing a custom PerRowSecondaryIndex and I managed to extract all
data I need but clustering columns values from cell names. I know that they are
part of the cell name itself and it's easy to extract the CQL column name:
public static String cellNameToString(CFMetaData metadata, Cell cell)
throws CharacterCodingException {
if (metadata.isCQL3Table()) {
return
ByteBufferUtil.string(cell.name().cql3ColumnName(metadata).bytes);
But I don't understand how to extract the clustering column values from cell's
name. Could someone share some info about that?
Thank you,
