PHP

• scylladb-php-driver: A modern, feature-rich PHP client library for ScyllaDB and Apache Cassandra, utilizing Cassandra's binary protocol. It supports PHP 8.1 and 8.2, and offers features like shard-aware routing, support for various CQL data types, and async query execution. The driver can be installed from source or using Docker for testing environments​ (GitHub)​​.
• ScyllaDB Alternator PHP Example: This example demonstrates how to use the AWS SDK for PHP to interact with ScyllaDB's Alternator, a DynamoDB-compatible API. It includes examples of creating tables, adding items, listing items, and deleting items in ScyllaDB using PHP​ (ScyllaDB Getting Started)​.

JavaScript

• ScyllaDB Driver for Node.js: A modern, fully-featured ScyllaDB driver for Node.js and TypeScript. This driver supports synchronous and asynchronous operations, connection to ScyllaDB clusters, query execution, load balancing policies, retry policies, speculative execution, metrics, logging, and schema inspection. It is designed to work with Node.js versions 18.x and above​ (GitHub)​.
• Getting Started with ScyllaDB Cloud Using Node.js: A step-by-step guide to building a simple Node.js application with ScyllaDB Cloud. The tutorial covers setting up the environment, creating a cluster, connecting to the cluster, and performing CRUD operations using JavaScript​ (ScyllaDB)​.
• IoT App with JavaScript: This tutorial demonstrates building an IoT application that uses ScyllaDB as the backend database. It includes instructions on setting up the database schema, simulating sensor data, and periodically saving data to the database using Node.js​ (ScyllaDB IoT)​.

Clojure

• Alia: A modern and high performance Cassandra and ScyllaDB client for Clojure, wrapping the Java Driver from DataStax, supporting CQL3, raw queries, prepared statements, synchronous and asynchronous query exectuion, asynchronous interfaces using either clojure/core.async, extensible Clojure data types. The driver can be installed from source or using the Clojars package.

Python

• ScyllaDB Driver for Python: A modern, feature-rich and highly-tunable Python client library for Scylla Open Source (2.1+) and Apache Cassandra (2.1+) and Scylla Enterprise (2018.1.x+) using exclusively Cassandra's binary protocol and Cassandra Query Language v3. This driver supports Python versions 3.6-3.11.
• Getting Started with ScyllaDB Cloud Using Python: A step-by-step guide to building a simple Python application with ScyllaDB Cloud. The tutorial covers setting up the environment, creating a cluster, connecting to the cluster, and performing CRUD operations using Python.
• Scylla cqlsh: Command line tool to connect to ScyllaDB (or Apache Cassandra). A fork of the cqlsh tool from https://github.com/apache/cassandra.

Java

• ScyllaDB Driver for Java: A modern, feature-rich and highly tunable Java client library for Apache Cassandra (2.1+) and using exclusively Cassandra's binary protocol and Cassandra Query Language v3. This driver supports synchronous and asynchronous operations, connection to ScyllaDB clusters, query execution, parallel execution, request pipelining, auto node discovery, automatic reconnection, configurable load balancing and retry policies, object mapper, and work with any cluster size. The driver can be installed from source or using the package from Maven Central.
• Getting Started with ScyllaDB Cloud Using Java: A step-by-step guide to building a simple Java application with ScyllaDB Cloud. The tutorial covers setting up the environment, creating a cluster, connecting to the cluster, and performing CRUD operations using Java.
• Scylla CDC Source Connector: Scylla CDC Source Connector is a source connector capturing row-level changes in the tables of a Scylla cluster. It is a Debezium connector, compatible with Kafka Connect (with Kafka 2.6.0+) and built on top of scylla-cdc-java library. The connector reads the CDC log for specified tables and produces Kafka messages for each row-level INSERT, UPDATE or DELETE operation. The connector is able to split reading the CDC log accross multiple processes: the connector can start a separate Kafka Connect task for reading each Vnode of Scylla cluster allowing for high throughput. You can limit the number of started tasks by using tasks.max property.
• Scylla CDC Java: scylla-cdc-java is a library that makes it easy to develop Java applications consuming the Scylla CDC log. The library automatically and transparently handles errors and topology changes of the underlying Scylla cluster. It provides a simple API for reading the CDC log, as well as examples and ready-made tools, such as replicator.

Elixir

• Xandra: A modern, Cassandra and ScyllaDB driver built natively in Elixir and focused on speed, simplicity, and robustness. This driver works exclusively with the Cassandra Query Language v3 (CQL3) and native protocol v3, v4 and v5. This driver can be installed from source or using the hex package.
• Getting Started with ScyllaDB Cloud Using Elixir: A step-by-step guide to build a simple Elixir application with ScyllaDB Cloud. This tutorial covers setting up the project, connecting to the cluster, and performing CRUD operations using Elixir.
