Reverse engineering from Hive database processing is slow due to the absence of system
tables. The required information is retrieved by manual parsing methods instead of a query language.
- The 64-bit OS version of erwin DM has access to greater memory and that could help with the performance. So make sure you are using that (the Help | About will tell).
- The processing power of a machine could also help with the performance.
- Finally, we have an import bridge for Hive also. That may also be an option for you: File | Import from external format. Then you can select the Hive bridge (an example is in figure 1, below).
Our suggestion is you run the reverse engineer over a weekend.
