Notes

Data types

Right now, int is used for the type of identifier. If the scale factor is very large, bitint is needed.

Because we may need to to compare the current version of Hive with a older version (e.g. 0.10.0) of it, we have to use data types supported by the older version to create columns. Here are mappings:

  • decimal -> float
  • char -> string
  • vacahr -> string
  • date -> string
