The Cassandra Java Driver Session object is a pool of connection objects. Typically, for most of the applications, one session object is sufficient per keyspace
. We can customize pool configuration using the PoolingOptions
object. While creating a Cluster
object, we can customize load balancing, Reconnection
policies, and Retry
policies according to our needs. Read and write operations can be done both in synchronous and asynchronous manners. Prepared statements can provide a slight performance gain for queries which are executed frequently, as they are parsed only time by database. The mapping API can be used to map Java POJO
classes to Cassandra tables. It enables APIs to perform basic CRUD operations on those POJO
classes. For complex query operations, we need to create an interface annotated with the @Accessor
annotation. We can enable tracing in Java Driver on a per-query basis.
