The Enumerated annotation If your class contains an enum type field, you use the Enumerated annotation. I have a Java enum and I want to use the @Enumerated annotation, but I can't seem to find it in 3.0.0 version of the driver, it was present in 2.1.9. $ find . -type f -name \*.jar|while read i; do echo ====== $i =====; jar -tf $i|grep Enumerated; done ====== ./cassandra-driver-core/2.1.4/cassandra-driver-core-2.1.4-javadoc.jar ===== ====== ./cassandra-driver-core

I am a newbie moving from the Mapper + Accessor approach to BoundStatement approach and would like to continue using the domain objects' Java classes built with the Object-mapping API so I do minimal changes to the implementation of my DAO methods while moving to the BoundStatement. I am looking to do it in a generic way and avoid to iterate over each ResultSet row and do a row.get one by one for each domain

I need to write in Batches to Cassandra using Datastax Java driver and this is my first time I am trying to use batch with datastax java driver so I am having some confusion - Below is my code in which I am trying to make a Statement object and adding it to Batch and setting the ConsistencyLevel as QUORUM as well. Session session = null; Cluster cluster = null; // we build cluster and session object here and we use DowngradingConsistencyRetryPolicy as well // cluster = builder.withSocketOptions(socketOpts).withRetryPolicy(DowngradingConsistencyRetryPolicy.INSTANCE) public void insertMetadata

Here is my CQL table: CREATE TABLE user_login ( userName varchar PRIMARY KEY, userId uuid, fullName varchar, password text, blocked boolean ); I have this datastax java driver code PreparedStatement prepareStmt= instances.getCqlSession().prepare("INSERT INTO "+ AppConstants.KEYSPACE+".user_info(userId, userName, fullName, bizzCateg, userType, blocked) VALUES(?, ?, ?, ?, ?, ?);"); batch.add(prepareStmt.bind(userId, userData.getEmail(), userData.getName(), userData.getBizzCategory(), userData.getUserType(), false)); PreparedStatement pstmtUserLogin = instances.getCqlSession().prepare("INSERT
