Data security is a very important issue in today’s world and one of the mechanisms Cassandra provides in this area is SSL encryption and authentication.
In the DataStax Test Engineering group we’re always working to provide better testing and developer enablement tools for the Cassandra project.
We are pleased to announce the 2.0 release of the DataStax C/C++ driver for Apache Cassandra and DataStax Enterprise. This release includes several new major features, mainly a latency aware routing policy and the addition of performance metrics, and improvements to the API including the removal of wrapper types (CassString, CassBytes, and CassDecimal), in favor of using plain C types, and the addition of string conversion functions for CassInet.
It has been a few months since DateTieredCompactionStrategy made its way into Cassandra 2.0.11 and then into DataStax Enterprise 4.0.5. Since then, we’ve been able to learn quite a bit about it.
The seamless integration between Cassandra and Solr that is provided by DataStax Enterprise (DSE) allows Cassandra columns to be automatically indexed by Solr through its secondary index API, as the picture below (click to enlarge) from DataStax Enterprise Documentation: Each insert or update of a Cassandra row triggers a new indexing on Solr, inserting or updating the document that corresponds to that Cassandra row.
