I think an eclipse plugin would be the wrong way to go here. Most people
probably just want to browse through the columnfamilies and see whether
their queries work out or not. This functionality is imho best implemented
as some form of a light-weight editor, not a full blown IDE.
I do have somethi
Thanks Ed, for the clarifications
Yes you are correct that the apps have to handle repeatable reads and not
the databases themselves when using absolute offsets, but SQL databases do
provide such an option at app's peril!!!
"Slices have a fixed size, this ensures that the the "query" does not

We should build an eclipse plugin named Eclipsandra or something.

Hinted Handoff is broken in your version [1] (and all versions between
1.0.0 and 1.0.3 [2]). Upgrade to 1.1.

I have a 4 node cluster, version 1.1.2, replication factor of 4,
read/write consistency of 3, level compaction. Several questions.
1) Should nodetool repair be run regularly to assure it has
completed before gc_grace? If it is not run, what are the exposures?
2) If a node goes down
Hi all,
I'm happy to announce a new release of cassandra-sharp (version 2.0-alpha),
a .NET client for Cassandra - all bits are available at
http://code.google.com/p/cassandra-sharp/.
This version is quite special because only the CQL Binary Protocol interface
is supported ! Yes, Thrift is d
Is there an IDE for a Cassandra database? Similar to the SQL Server
Management Studio for SQL server. I mainly want to execute queries and see
the results. Preferably that runs under a Windows OS.
Thank you.
Does the official/built-in Cassandra CQL client (in 1.2) offer any built-in
option to get direct values/objects when reading a field, instead of just a
byte array?
Here is an example of the increase for some counter (counting events per
hour)
time (UTC) 0 1 2 3 4 5 6 7 8 9 10 11 12 13
Good value 88 44 26 35 26 86 187 251 455 389 473 367 453 373

Update on this: someone just pointed me towards the Cequel gem:

The way it's described in the readme it looks like exactly what I was
looking for - a modern, CQL-based gem that is in active development and
also follows the ActiveModel pattern. I'd be very intere

Can you provide an example of the increase ?
Can you provide the log from startup ?

If the startup is taking a long time or not working and you believe it
to be corrupt in some way it is safe to delete the saved cache files.
If you think the process is taking longer then it should you could try
attaching a debugger to the process.
I try to avoid the row cache these days, even wit
There are several reasons. First there is no "absolute offset". The
rows are sorted by the data. If someone inserts new data between your
query and this query the rows have changed.
Unless you doing select queries inside a transaction with repeatable
read and your database supports this the query
We just upgrade to C* 1.1.6
We can now change anything using the CLI or cqlsh. So problem solved.
