Hi, I am new to Cassandra, we are planning to use Cassandra for cloud base application in our development environment, so for this looking forward for best strategies to sync the schema for micro-services while deploy application on cloud foundry
One way which I could use is Accessor interface with datastax-mapper and casandra-core driver. 1.) I have created a keyspace using core driver which will be generated on initialization of servlet *public* *void* init() *throws* ServletException { Cluster cluster = Cluster.*builder*().addContactPoint("127.0.0.1").build(); Session session = cluster.connect(); String keySpace="sampletest"; session.execute("CREATE KEYSPACE IF NOT EXISTS "+ keySpace + " WITH REPLICATION = { 'class' : 'SimpleStrategy', 'replication_factor' : 1 }"); .............. 2.) This is my Accessor Interface which I used to generate Query for creating column family .......... @Accessor *public* *interface* UserAccessor { @Query(" CREATE TABLE sampletest.emp (id uuid PRIMARY KEY,name text,department text,location text,phone bigint ) WITH caching = '{ \"keys\" : \"ALL\" , \"rows_per_partition\" : \"NONE\" }' " ) ResultSet create_table(); } 3.) Creating an instance of Accessor interface to provide mapping to our query to generate column family ................ MappingManager mapper=*new* MappingManager(session); UserAccessor ua= mapper.createAccessor(UserAccessor.*class*); ua.create_table(); ................ 4.) So far I have created a keyspace with a column family , now I want to map my data using POJO class mentioned below @Table(keyspace = "sampletest", name = "emp") *public* *class* Employee { @PartitionKey *private* UUID id; *private* String name; *private* String department; *private* String location; *private* Long phone; // getter setter method ................. } Is there any other better approach to achieve this especially for cloud environment -- Thanks Ankit Agarwal
