Hi folks,
I am reading RocksDBStore.cc <http://rocksdbstore.cc/> and trying to understand how
the iterator works. I found myself positively puzzled by the implementation of
lower_bound() and upper_bound() of CFIteratorImpl. It seems to be that upper_bound()
doesn’t really set the upper bound for iteration. Instead, it just resets the lower bound,
presumably to a more advanced position after the initial lower_bound() call, since it
calls lower_bound(). It doesn’t reset the true upper bound, which is set in
iterate_upper_bound and used by RocksDB.
Is my understanding correct or am I missing something?
Thanks,
Yixin
