Hi. I'm considering creating a table using FastBit that has many boolean columns, but it appears that the 8 bit char types are the most compact format available. I could pack them into an unsigned long int, rather than store them as separate shorts, but queries on such a column (e.g., "packedflags & 0100101001 != 0") would not be able to take advantage of the index.
I have 2 questions. 1. Are queries like that even possible in FastBit? 2. Is there a space and time efficient way to represent and query these boolean variables? Thanks, Andrew _______________________________________________ FastBit-users mailing list [email protected] https://hpcrdm.lbl.gov/cgi-bin/mailman/listinfo/fastbit-users
