Spring Boot, Kotlin, and Reactive Scylla sample project

Spring Boot with Kotlin and Reactive Cassandra

Example of Spring Data Cassandra with Reactor.

Quick start

This guide use ScyllaDB implementation of Cassandra.

First, instantiate a ScyllaDB container.

    docker run --named scylla-test -p 127.0.0.1:9042:9042 -d scylladb/scylla
    docker start scylla-test

Next, install CQL shell (require Python 2):

    pip install cqlsh

Connect with Scylla:

    cqlsh 127.0.0.1 9042

Check if Scylla actually works:

    cqlsh> select release_version from system.local;
    
     release_version
    -----------------
               3.0.8
    
    (1 rows)

To run this project, create a new keyspace named mykeyspace:

    create keyspace mykeyspace with replication = { 'class' : 'SimpleStrategy', 'replication_factor' : 1 };

Edit application.properties accorddingly.
