Subject Re: Wide rows in CQL 3
Date Thu, 10 Jan 2013 12:58:46 GMT
Thanks for explaining, Sylvain.You say that it is "not a mandatory
one", how long could we expect it to be "not mandatory"?I think the
new CQL stuff is great and I will probably use it heavily.  I
understand the upgrade path, but my question is if I should start
planning for an all-CQL future, or if I still could make some CFs with
thrift and also expect it to work in 3 years time.  You say "you
should see CQL3 non compact tables as the new stuff, the thing that
you use post-upgrade" - but doesn't that mean that we also have to
suddenly depend on a schema?  Let us for example say you have a
logger, which logs all kinds of different stuff - typically key-value
- and that each row could contain different keys.    ROWKEY1:
 key1: val1, key2: val2, key3: val3ROWKEY2:  key4: val4, key1: val2,
keyN: valN
Is this possible without using multiple rows in CQL3 non compact
tables?  
.vegard,

I'd be clear, CQL3 is meant as an upgrade from thrift. Not a mandatory
one, you
 can stick to thrift if you don't think CQL3 is better. But if you do
decide to  upgrade, you should see CQL3 non compact tables as the new
stuff, the thing that you use post-upgrade. While you upgrade, stick
to compact tables. Once you've upgraded, then you can start using the
new stuff and accessing the new stuff the old way doesn't matter.
