Re: get_slice needs offset

2011-07-06 Thread Boris Yen
I suppose what you meant is to use the last-column-seen as the "start" of SliceRange to make another query, so that the server could use the per-row column index to jump to the right position of a file and retrieve column data. Based on that, if an application/cassandra-client wants to implement a

Excellent idea indeed, I have been looking for such tickets as well :) I take the chance to introduce myself to the list btw, I'm currently getting my toes wet in Cassandra, developing (mostly) in python, and willing to contribute - I'm not there yet though; will have a look at the LHF tickets for

RPMs made easy

Hi all, I'm new to the realm of Cassandra and I'm just starting to get to know the tool you've been working on. I wanted to try it out on my laptop (CentOS 5.6) and found that getting an RPM for installation was "hard". Also building one from source was not quite as easy as I would like it to be.

Re: Reoganizing drivers

2011-07-06 Thread Jonathan Ellis
I don't think this is working out as well as hoped. - the git mirror won't pick up anything under drivers/ - building the Java drivers is fragile and complicated, and there's a lot of duplication with the "main" ant build - patches that affect both Cassandra and JDBC are cumbersome since they have

Re: get_slice needs offset

It was removed because the "right" way to do this is to page by last-column-seen, which can take advantage of the per-row column index. Offset cannot. On Wed, Jul 6, 2011 at 3:04 AM, Boris Yen wrote: > Hi, > > It seems it was implemented before. However, due to Cassandra-286, it was > removed. I

get_slice needs offset

2011-07-06 Thread Boris Yen
Hi, It seems it was implemented before. However, due to Cassandra-286, it was removed. I was wondering if it is possible to put it back. Because computing the offset on the client side should be less efficient than do it on the server side. I am thinking this might be possible to achieve by tweak
