Re: HowTo: Range scan on secondary indexes?

Ah ok, so i have to build a hash index to get all relevant data sets first, than cassa performs the range scan. Good to know, thx a lot! :o) 2010/11/14 Jonathan Ellis > Because 0.7.0 indexes are more like a Hash index than a B-tree. > > On Sun, Nov 14, 2010 at 12:39 PM, André Fiedler

Re: Facebook messaging and choice of HBase over Cassandra - what can we learn?

Doesn´t sync Cassandra all nodes if the network is up again? I think this was one of the reasons, storing a timestamp at every key/value pair? So i think the response will only temporary be 11. If all nodes have synct it should be 12? Or isn´t that so? greetings André 2010/11/22 Samuel Carrière

Re: Using mySQL to emulate Cassandra

If you want to do this, don´t use autoincrementing integers! ;o) Use UUID instead. (or implement an stand alone id-server that handles autoincrement savely) 2010/11/28 David Boxenhorn > As our launch date approaches, I am getting increasingly nervous about > Cassandra tuning. It is a mysterious
