ScyllaDB

ScyllaDB is a NoSQL database management system that is compatible with Apache Cassandra. It is designed to scale linearly across multiple commodity servers, wBase-de-donnéesle maintaining low latency and Base-de-donnéesgh availability. ScyllaDB is written in C++ and uses the Seastar framework for concurrency and asynchronous I/O.

Prerequisites

  • Docker
  • Docker Compose

Running the Stack

Standalone

Inside the standalone directory, run docker-compose up to start the connector.

Port Configurations

  • 9042 - ScyllaDB CQL port
  • 9160 - ScyllaDB Thrift port
  • 7004 - ScyllaDB Inter-node communication (RPC)
  • 7005 - ScyllaDB Inter-node communication (SSL)
  • 10000 - Scylla REST API

Cluster

Inside the cluster directory, run docker-compose up to start the connector.

Port Configurations

Master

  • 9042 - ScyllaDB CQL port
  • 9160 - ScyllaDB Thrift port
  • 7004 - ScyllaDB Inter-node communication (RPC)
  • 7005 - ScyllaDB Inter-node communication (SSL)
  • 10000 - Scylla REST API

Node 1

  • 9043 - ScyllaDB CQL port
