Howdy,
As a followup to my earlier thread I wanted to share some of our
experimental data using an auto-tuning agent to find optimal thread pool
settings for C*. The results surprised me. It invalidated a lot of previous
thinking about tuning C* and calls into question some of the decisions that

Howdy,
I’ve been engaged in the Cassandra user community for a long time, almost 8
years, and have worked on hundreds of Cassandra deployments. One of the
things I’ve noticed in myself and a lot of my peers that have done
consulting, support or worked on really big deployments is that we get
burnt
If I create a column family with a comparator of:
DynamicCompositeType(a=>UTF8Type,b=>UTF8Type,c=>UTF8Type,t=>TimeUUIDType)
Can I do an insert that has a column where a,b,c,t are set and an insert with
a,b,t are set, or must I always set values for colums a,b,c,t?
If I must always set values
Ah yes, I should clarify. What I should have said was an ORM type library
which uses cassandra-cql as it's base. What I was looking for was someone that
had wrapped cassandra-cql with an active record or data mapper compatibility
layer.
My concern is that it i'm looking for a ruby client th
Howdy,
I'm working on transferring an existing Ruby on Rails project from Postgres to
Cassandra and I have a couple questions about the Ruby client libraries and
client libraries in general.
1.) Is it the opinion of the community and the Datastax engineers that client
libraries should migrate

This sounds like an LDAP prob

Am I crazy to want to switch our server's primary data store from postgres to
cassandra? This is a system used by banks and governments to store crypto keys
which absolutely can not be lost.
Hi, I have a question about Cassandra's data model I was hoping you guys could
help me with. Most of our queries are performed against a series of tables
containing crypto keys and their associated meta data. A key could have any
number of identifiable attributes that need to be searchable: ia
