Hallo,
we work with Cassandra version 3.0.9 and have a problem in a table with TWCS.
The command "nodetool repair" create always new files with old data. This avoid
the delete of the old data.
The layout of the Table is following:
cqlsh> desc stat.spa
CREATE TABLE stat.spa (
region int,
Hi all,
# Sorry, I accidentally emailed the following to dev@, so re-sending to here.
We have been working on ACID-compliant transaction library on top of
Cassandra called Scalar DB,
and are pleased to announce the release of v.1.0 RC version in open source.

This is great!

Hi,
Yes this does sound great. Does this rely on Cassandra's internal SERIAL
consistency and CAS functionality or is that implemented at a higher level?

I think it does use LWT under the hood:
https://github.com/scalar-labs/scalardb/blob/master/src/main/java/com/scalar/database/transaction/consensuscommit/CommitMutationComposer.java#L74-L79
return new Put(base.getPartitionKey(), getClusteringKey(base,
result).orElse(null))
.forNamespace(b
It looks like it's based on this:

Your dashboards are great. The only challenge is getting all the data to
feed them.

Hi all,
Thank you for the comments and feedbacks.
As Jonathan pointed out, it relies on LWT and uses the protocol
proposed in the paper.
Please read the design document for more detail.

Regarding the licensing, we are thinking of
