NOTE: If I use Long.MAX_VALUE instead, I get the records.
I can hack this at the app layer, to issue separate queries for the wrap
around case, but I wonder if CQL should support wrap around queries???

Looks like the java-driver supplies the hack I need. (TokenRange.unwrap)
I¹ll leave it to you guys to decide if it is more elegant to support
wrapping natively in CQL.

I'm using the following schema and data:
CREATE TABLE children ( childId varchar, firstName varchar, lastName
varchar, timezone varchar, PRIMARY KEY (childId ) );
insert into children (childId, firstName, lastName, timezone) values
('bart.simpson', 'Bart', 'Simpson', 'PST');
insert into children (c
e)
I think I can explain away the empty row/column, but we should probably
publicize that. I can see that question coming up on every client/api
user list. (hector, astyanax, etc.)

FYI -- I'm still seeing this on 1.2-beta1.
If you create a table via CQL, then insert into it (via Java API) with
an incorrect number of components. The insert works, but select *
from CQL results in a TSocket read error.
I showed this in the webinar last week, just in case people ran into
it.
Will do.

How does this compare with Druid?
https://github.com/metamx/druid
We're currently evaluating Acunu, Vertica and Druid...
http://brianoneill.blogspot.com/2013/04/bianalytics-on-big-datacassandra.html
With its bitmapped indexes, Druid appears to have the most potential.
They boast some pretty im

this.
(Acunu provides most of the capability, but it isn't open source)
I think once we have the "conditional write" semantics that are coming, we
could layer this on top of C*. (extending the secondary indexes
functionality)

I¹m +1.
We¹ve had one foot out the door for a while now.
We are throwing resources at CQL. (e.g. storm-cassandra-cql) And we are
slowing support for the thrift-based implementation (e.g. storm-cassandra).
Alas poor Thrift, I knew him (well).

Jeremy/Jonathan,
When you finish celebrating the 1.0 release, I just submitted a native rest
layer for Cassandra.
https://issues.apache.org/jira/browse/CASSANDRA-3380
It uses JAX-RS and Apache CXF supporting the following operations (JSON over
HTTP):
- Create keyspace
- Drop keyspace
-
I just sent an email out over the users list.
Over a couple nights this week, I added SOLR integration into Virgil.
(Virgil is that REST layer that we've been building out over in Apache
Extras)
I just wanted to through an idea out to the dev list...
I plan to migrate the current implementation i
Understandable. I'll leave it as is then in the REST layer.

I'm by no means a git guru, but just happened to attend a meeting last
night where the presenter addressed this exact issue. He has a pretty
slick process that kept the master/trunk clean without rebasing by
squashing a set of commits into a single commit when merged to trunk.
(using git squash?)
I just posted to the user list, but figured I would post here as well.
We had a big session today designing application-level triggers using a new
column family as a distributed commit log.
When I got back to my desk, I re-googled Cassandra triggers, and re-read:
https://issues.apache.org/jira/bro
Today, running 1.0.7, we saw a node crash with an OutOfMemory.
We have a single row with ~10million columns in it. (using it as an index)
Accidentally, we attempted to list the CF in CLI that had the wide-row.
This caused the CLI to hang and then eventually crashed Cassandra with an
OoM.

here.
Or do we pass back some other structure? (Native lists/maps? JSON

Do we ignore sorting/comparators?
