Re: Issues with MonetDB
Dear Ashish, thank you very much for your feedback. Did you already try Oct2012-SP2, upcoming Oct2012-SP3 (currently available from http://dev.monetdb.org/downloads/testing/ ; will be formally released soon), or the Feb2013 branch from Mercurial (http://dev.monetdb.org/hg/MonetDB/branches)? To be able to further debug the problem on our side, we would need all the ingredients required to reproduce the problem you're experiencing (code, data, queries, detailed instructions).

First of all performance improvements are really great using monetdb but we are facing some issues related to data consistency as described below: 1. Duplicate tuples are getting inserted few times. 2. Updates to database are not available for read immediately , sometimes wrong values are returned by database. After certain number of retires these becomes available though can go to 10 times of retires. We are facing this for Oct 2012 Sp1 build. These data related bug are not acceptable in our usage scenario and this will be the case with other folks too! Question to the list is there any released version backwards / upwards which can be used instead of October 2012 Sp1 which does not have these issues? I have filled a bug also for this at http://bugs.monetdb.org/show_bug.cgi?id=3222 Regards, Ashish
Thanks Stefan and Niels, I have attached a test case for Duplicate tuples are getting inserted few times issue mentioned below to bug id 3222 with instructions on how to use it. http://bugs.monetdb.org/show_bug.cgi?id=3222 Any help on this will be greatly appreciated!
