Re: Data model names, reloaded

2009-08-21 Thread Sandeep Tata
Evan, PS. The implementation of column families hasn't changed from BigTable, but the use in modeling has. Common Cassandra designs are more row-oriented than column-oriented. I'm not sure I understand the distinction you're drawing between row-oriented modeling and column-oriented modeling.

There is some (unfinished) code in the current repo on CQL a SQL-like Cassandra Query Language that is super simple and (AFAIK) limited to single node queries. I suspect there are bigger questions to tackle before we get to query lanuages in the sense we're talking about-- 1. Data model --

Re: proposal: rename table to namespace

2009-06-20 Thread Sandeep Tata
I'd like for us to continue with Table as well. I agree with Alexander's argument for what namespaces mean for most CS domains. Moving up a notch to a database is also confusing (Do we also have tables? Are there tablespaces? Different storage engines for each tablespace?) We'll have to think of

Won't things like multi-table support break binary compatibility anyway? We might be stuck with having to write a tool that migrates from a 0.3 format to a 0.4 format. On Wed, Jun 3, 2009 at 2:44 PM, Jonathan Ellis jbel...@gmail.com wrote: The fix for 208 [1] is fairly invasive.  should we

Re: could cassandra be split into two parts?

2009-04-11 Thread Sandeep Tata
Depends on what exactly you have in mind ... Almost all of the storage engine logic is in the db package. I don't think it would be too hard to make this pluggable so you could slide in your own DB, say based on Derby/MySQL/BDB etc... I can see how specialized implementations of the database part
