I have just release version 0.3.5 of my Cassandra Connection Pool.
It contains a couple of bug-fixes when setting configuration properties via the generic set() method and much improved logging: all logs are prefixed with the pool’s name, periodic activity is lowered at trace from debug, and extra logging is done on pool exhaustion.
I recommend upgrading to it.
Get it from my Maven repo.
Cassandra Connection Pool 0.3.3 includes a few bugfixes and some logging (at debug level) for helping to identify problems with validation.
A few days ago I release version 0.3.2 of Cassandra Connection Pool. It fixes a couple of bugs.
I have just released version 0.3.0 of my Cassandra Connection Pool.
New features in this release are:
- automatic host discovery with connection failover
- datasource implementation
- cleanups and bugfixes
The Cassandra CacheStore will be included in the Infinispan 4.2, so that people won’t have to wait until 5.0.
Since I have been accepted as an Infinispan contributor, I have committed my first complete implementation of the Cassandra CacheStore to Infinispan’s trunk. This means that it will be included in Infinispan 5.0 whenever that will be released.
In the meantime I have migrated all the code into my repository and have released a 0.0.2 version which can be used with the current Infinispan 4.1.x and 4.2.x. The Maven dependency (if you use my repository) is:
I would be very grateful if you could test it in your environment.
I am also working on adding multiple host addresses and automatic ring discovery to my Cassandra Connection Pool.
Since my previous post about the Cassandra Connection Pool, I have been progressing on another project: a Cassandra CacheStore for Infinispan.
I have published on my personal SVN repository the initial source for this CacheStore, get it at:
If you use Maven, add my repository to your settings.xml or to your repository manager (Nexus, Artifactory, etc):
which contains all required dependencies.
See the tests available under src/test for examples on how to setup an Infinispan cache backed up to a Cassandra database and how a Lucene InfinispanDirectory can take advantage of both systems.
I am working on rearranging things for potential inclusion in the main Infinispan package, so some things may change (package names). Also key expiration is not as efficient as I would like, but release early, release often is good practice, so there 🙂
For a project of mine I’ve had need for a robust, decent connection pool for Cassandra. Since I use the thrift APIs directly without other layers, I decided to use Tomcat 7’s excellent jdbc-pool as a base. The result is my cassandra-connection-pool which at the moment may be fetched from my github repository at http://github.com/tristantarrant/cassandra-connection-pool
It supports most of the features of its parent implementation: connection validation on creation, release and idle, abandoned connection detection, etc.
Let me know if you use it.
