CACHE_LINE_SIZE

#define CACHE_LINE_SIZE   64

Definition at line 27 of file tuple_buffer.h.

CHAINEDBUFF_NUMTUPLESPERBUF

#define CHAINEDBUFF_NUMTUPLESPERBUF   (1024*1024)

Definition at line 20 of file tuple_buffer.h.

SORTED_MATERIALIZE_TO_FILE

#define SORTED_MATERIALIZE_TO_FILE   0

If rid-pairs are coming from a sort-merge join then 1, otherwise for hash joins it is always 0 since output is not sorted.
