Dear all, I am a newbie to Fastbit and I am not familiar with database manipulation, so please don't mind if my questions are non-sense. I am trying to understand Fastbit to accelerate part of the query process. In order do to this, I need to somehow port the whole bitmap indexes of a database to another platform and perform bitwise operations there (hopefully by accelerating these bitwise operations, I can accelerate the query process). I have the following questions:
1. Is there any available function in Fastbit that can write the bitmap indexes of a data partition into a text file? I guess that after performing an ardea command on a database.cvs file, then performing an ibis command with option -b then the bitmap indexes are created in file.idx. Is this correct? And if yes, how to process this further or read the file into a variable to further manipulate the database? 2. While a query is performed, except from bitwise operations, is there any operations needed to optimize the bitmap indexes of the database? In other words, is the database changed during a query is performed? I am looking forward to your response. Thank you very much! Best Regards, Anh
