ScyllaDB is a distributed NoSQL database that is designed to provide high performance and low latency. It is based on the Apache Cassandra project but is designed to be faster and more scalable. ScyllaDB is written in C++ and uses a shared-nothing architecture, which means that each node in the cluster is independent and does not share resources with other nodes. This allows for better performance and scalability since each node can be optimized for its specific workload.
ScyllaDB supports the CQL (Cassandra Query Language) API and provides features such as automatic sharding, automatic replication, and built-in support for secondary indexes. It also supports features such as transactions and materialized views. ScyllaDB is commonly used in applications that require high throughputs and low latency, such as real-time analytics and ad-serving platforms.
Install the cassandra-driver package and execute the following code:
from cassandra.cluster import Cluster
# Connect to the ScyllaDB cluster
cluster = Cluster(['localhost'])
session = cluster.connect()
# Create a keyspace
session.execute("CREATE KEYSPACE IF NOT EXISTS mykeyspace WITH replication = {'class': 'SimpleStrategy', 'replication_factor': '1'}")
# Create a table
session.execute("CREATE TABLE IF NOT EXISTS mykeyspace.mytable (id uuid PRIMARY KEY, name text)")
# Insert some data
session.execute("INSERT INTO mykeyspace.mytable (id, name) VALUES (uuid(), 'John Doe')")
session.execute("INSERT INTO mykeyspace.mytable (id, name) VALUES (uuid(), 'Jane Doe')")
# Retrieve data
rows = session.execute("SELECT * FROM mykeyspace.mytable")
for row in rows:
print(row.id, row.name)
# Close the session and cluster
session.shutdown()
cluster.shutdown()
This example connects to a ScyllaDB cluster running on localhost, creates a keyspace named mykeyspace, creates a table named mytable, inserts some data into the table, retrieves the data, and then closes the session and cluster.
