I have some questions about SciDB as follows:
I have see the issue http://www.scidb.org/forum/viewtopic.php?f=13&t=1259 ,and I have a question about that if I execute like " select … where VA> 22 and VA < 9999" statement, what’s the SciDB storage do ? I know SciDB can quickly find the cell by block partitioning algorithm , but how does SciDB determine the position of VA’s value( =22 or 9999) ? sequential scans in the chunks ? I mean, how does SciDB storage find the value’s(such as 22 or 999) position ?
I compiled the SciDB source (14.12) with SciDB_Build_Instructions_14.12, but I do not know how I will do to debug the SciDB source because I am new to debug. Could you please give me some advise? maybe examples that debug the SciDB?
when I use gdb it display some informations:
“no debugging symbol found…” so I do not know if there is something like “–enable-debug” parameter when compile the SciDB ?
