Hi,

Well, that was a word to word quotation. :)

Anyways, I think what you just said is a better explanation than those two previous ones. I hope it ends up on the wiki page because what it says there now is causing confusion, no matter how correct it technically is :)

Cheers,

Well, I don't know if that's what Patrick replied but that's not correct. The wording *is* correct, though it does uses CQL3 terms.
For CQL3, the term "partition" is used to describe all the (CQL) rows that share the same partition key (If you don't know what the latter is: http://cassandra.apache.org/doc/cql3/CQL.html).
So it says that all the rows sharing a particular partition key multiplied by their number of effective columns is capped at 2 billions.

In the thrift terminology, this means a 'thrift row' (not to be confused with a CQL3 row) cannot have more that 2 billions thrift columns'.

I asked the same thing earlier and this is what patrick mcfadin replied: "It's not worded well. Essentially it's saying there is a 2B limit on a row. It should be worded a 'CQL row'"

I hope helps.

Hi,
In the above link, I found the below limitation,

"The maximum number of cells (rows x columns) in a single partition is 2 billion.".

Here what does "partition" mean ? Is it node (or) column family (or) anything else ?

Thanks,
Ramesh
