o now it's behaving :)
#define ntohll(x) (((_int64)(ntohl((int)((x << 32) >> 32))) << 32) |
(unsigned int)ntohl(((int)(x >> 32
string result;
result.resize(sizeof(long long));
long long bigendian = htonll(l);
memcpy(&result[0], &bigendian, sizeof(long long));
=> (super_column=1291668233,
uh, ok I was just copying :P
string result;
result.resize(sizeof(long long));
memcpy(&result[0], &l, sizeof(long long));
I'll try and let you know
many thanks!

I'm doing this in my C++ client so contact me offlist if you need code

Also, thought I should mention:
When you make a std::string out of the char[], make sure to use the
constructor with the size_t parameter (size 8).

That should be "big-endian".

How are you packing the longs into strings? The large negative numbers
point to that being done incorrectly.
Bitshifting and putting each byte of the long into a char[8] then
stringifying the char[] is the best way to go. Cassandra expects
big-ending longs, as well.

I'm using thrift in C++ and inserting the results in a vector of pairs, so
client-side-mangling does not seem to be the problem.
Also I'm using a "test" column where I insert the same value I'm using as
super column name (in this case the same date converted to string) and when
queried using cassa
What client are you using? Is it storing the results in a hash map or some
other type of
non-order preserving dictionary?

Hi, I've the following schema defined:
EventsByUserDate : {
UserId : {
epoch: { // SC
IID,
IID,
IID,
IID
},
// and the other events in time
epoch: {
IID,

Where I'm expecting to store all the event ids for a user ordered by date
(it's seconds since epoch as long long), I'm usin
