Is there any way to enable the multiple super column names at a time?

2010-04-11 Thread Dop Sun
Hi,

I don't know whether I have missed anything here, but can we get columns for
multiple Super Column Names at a time, like what we can do for Keys (by key
range or list of keys) or columns (by column range or column list)?

While I'm doing the work with Cassandra, I usually think the structure like
this:

KS - CF - Key - Super Column - Column

But looks like I should change it to something like:

KS - CF - Super Column - Key - Column

Since CF-SuperColumn are combined within a single parameter: ColumnParent,
and they are usually unique (single) in a query.

Regards,
Dop




Re: How is Cassandra being used?

I am not dev of cassandra, sub this list because i'm dev for app using it.

To me, this (phone home) opens a door, and it may designed to be used only for 
carefully selected anonymous data:
1) but software has at least one bug (side effect), what happen it sends 
something more accidentally? Also, even today data we believe safe, but 
tomorrow it may turn out to be classified as sensitive, and you can not take 
back data which already out of door.
2) risk for future versions, this forces all upgrades to include review of this 
anonymous data (if door opened, it is too easy to add a little bit next time, 
and next...), imagin every release, to invite compliance team to sign off... it 
may slow the adoption of new versions. And this does no good for heathy of 
Cassandra community/ user group.

As a user may not be right to vote here, but if I vote:
-1 for introducing this feature at all

But if it's eventually included:
+1 for separate code/ jar

Re: Build failed in Jenkins: Cassandra-quick #489

Hi,

I am using a rule in my mailbox settings (a kind of setting in the server side, 
usually can be found in web interface), to move the emails sent from that 
specific email address to some other folder.

And it works and safe, unless you really care about the building notification.

Hope it will help.

Regards,
Dop
