default sue compact serialize version.
bitmap index when Cardinality is large GetIndexDataSize will get very large size cause alloc failed exception.
in our case ,the bitmap index cardinality is 53583500, GetIndexDataSize will return 18446744071658782694. when use getSizeInBytes(false) that GetIndexDataSize will return 1794992794.
