Hi Pradeep, cracking is not implemented in MonetDB. It was only implemented as an experimental code. You could implement a standalone program if you want to perform measurements, the paper is very well written and explains most implementation details. MonetDB uses imprints for range queries (gdk/gdk_imprints.c/h and gdk/gdk_select.c). There is also a SIGMOD paper about imprints. You can also test/check this.

My questions are

1) Does cracking implemented in monetdb ?

2) Which file contains the code for cracking in source ?

3) Can we trace cracking and find whether query reads record from disc or the cracked columns ?

Thanks in advance.

regards , Pradeep.
