> ByteArrayList in Trafodion is an expensive class. Removing the use of this class everywhere. Replace its usage with array of byte arrays.
> This class is mainly used in compiler. Hence it is expected to see some improvement with compilation of queries when the tables involved in queries have large number of regions.
