Cassandra, a wide column store NoSQL database famous for its ability to distribute petabytes of data with unmatched reliability and performance.
It was created in 2008 by Avinash Lakshman, who was responsible for scaling Facebook's inbox search feature.
By 2010, became a top level Apache project, and today is used at scale by big companies like Apple, which manages a staggering 100 petabytes of data across 100 of thousands of server instances.
It's a general purpose database with use cases for e commerce, content management, audit logging, and everything in between.
Each instance of Cassandra is called a node, and typically stores about 2 terabytes of data.
What makes it special though is that nodes can be easily distributed to scale horizontally.
Every node has the same read write capabilities of another node, but is responsible for its own partition of data.
Nodes are grouped together in a cluster or ring, and data is typically replicated on multiple nodes, which means no single point of failure and 100% uptime.
The data is wrapped in a key space, giving developers rule over how it replicates in the cluster.
Each key space contains 1 or more tables, which represent tabular data like you might find in a relational database.
However, it's schema less and can handle unstructured data, which developers can manage with the Cassandra Query Language.
The easiest way to get started is by creating a free server database with Astra.
It deploys to the cloud of your choice, then scales automatically on demand.
1st, we'll need to define a key space, which access a container for replication.
Next, we'll need to connect to the database, which can be accomplished in a variety of ways.
It has SDKs for major languages, and a tool called star that makes data accessible via REST, GraphQL, and gRPC.
Or you can execute raw CQL code, which is a subset of SQL.
Create a table and include a primary key to uniquely identify every row.
Then each column will have its own name and data type.
Now add data to that table with the insert into statement.
Then you to read data from the table.
It's also possible to use the where clause to filter and query the data, but an index will be required on the column.
On the surface, this may look a lot like a relational database, but it doesn't support Joins and that's by design.
Instead of modeling data into small normal tables, in Cassandra, it's denormalized to match the structure of known queries, making reads much faster at scale.
And it's also possible to implement storage attached indexing to handle complex relational queries.

In this video, the host explains the benefits of using the new version of Cassandra, a general purpose database designed to store data on scale. The database is a cluster or ring, and can handle unstructured data. It can be used to access a single point of failure and handle uptime by allowing developers to manage and manipulate the data. The host recommends creating a free server database and using the default implementation of the new version, writing the data into a table and filtering and query the data.
