Hao Chen commented on EAGLE-190:
--------------------------------
No need to register additional complex jdbc type double[], because eagle
storage system support both hbase and jdbc, in hbase we would serialize
everything as binary, but in mysql, we would only register those type we don't
want to store directly as binary for example some fileds in primitive type like
String, Integer, Boolean and so on which could be filtered through sql query,
otherwise for those types we don't register like double[], it will be
serialized as binary and store as Types.BLOB physically.
