Hi, Everyone, After accumulating changes for more than four months, we are making another version of public release. This version is marked as ibis1.3.1. Just in case anyone is counting, it corresponds to SVN Revision 539. The new tar ball can be downloaded at <https://codeforge.lbl.gov/frs/download.php/394/fastbit-ibis1.3.1.tar.gz>
Thanks for all the contributions we have received. As always, please feel free to let us know if you find anything that requires attention. John Release Notes: This version completes a way to work with set-values through text columns, keyword indexes, and a new operator CONTAINS for query expressions. This feature is exercised through the tests defined in check-jrf and check-text. We have also implemented a work-around for I/O libary limitation on the number of bytes that can be read and written in one shot. This should let FastBit work with larger data partitions more fracefully. We are very thankful for many users who have worked patiently with us to fixed a number of nasty bugs. In particular, we would like to thank Greg Barker for a number of test cases in dealing with appending new data and purging inactive rows, Rock Wong and Matt Bomhoff for pointing out the I/O buffer limitations, and Gaurav Agarwal for fixing a bug with updating metadata of data patitions. We really appreciate all their contributions. Changes: Version ibis1.3.1 -- impelement ibis::util::read and ibis::util::write to get around the limitations with POSIX read and write functions in handling large buffers -- add UDT as a new data type for future expansion -- support for BLOB with ibis::opaque class -- process categorical values as integers in memory and on output, convert query conditions on categorical values to be integer comparisons -- add query expression with the operator "CONTAINS" to allow for a more consistent handling of keyword searches (also known as full-text search) -- reorganize -output option of ibis.cpp to add new flavors for -output-as-binary so that the resulting output can be used direct by FastBit (total three flavors: -output, -output-with-header, -output-as-binary) _______________________________________________ FastBit-users mailing list [email protected] https://hpcrdm.lbl.gov/cgi-bin/mailman/listinfo/fastbit-users
