Hi, Mehmet, Thanks for your interest in FastBit software; sorry that your message seemed to have got lost in my inbox.
You are right that FastBit is meant for read-only data. However, it is possible to append and even delete records. In the documentation of ibis::part class, you can find a number of functions related to this functionality. ibis::part::append for adding data to an existing partition (alternatively you can use ibis::tablex interface) ibis::part::deactivate for marking certain rows as not active (i.e., not eligible to participate in query answering) ibis::part::purgeInactive for reorganizing data and removing inactive rows. If you intent to add and delete a small number of rows at a time, FastBit is probably not the most appropriate tool for you. Good luck.
