Cassandra is a highly scalable, distributed database system that is designed to handle large amounts of data across multiple commodity servers. The underlying data model of Cassandra is based on the idea of a "column family", which is essentially a key-value store where each key has a set of named columns associated with it. One of the unique characteristics of Cassandra is its support for distributed data storage and replication. Data in Cassandra is distributed across multiple nodes in a cluster, with each node being responsible for storing and serving a subset of the data. This distributed nature allows Cassandra to handle large amounts of data and provide high availability and fault tolerance. Cassandra uses a peer-to-peer architecture to distribute data across nodes in the cluster.

I cannot speak for Apple but when you think about it, many fewer people will use a mouse with a laptop when the built in track pad is so close to hand. Go to Systems Prefs Accessibility Scroll down to mouse and track pad click on that and check the box at the bottom of the R H panel which says ignore track pad when mouse is present.

Cassandra uses a peer-to-peer architecture to distribute data across nodes in the cluster. Each node communicates with other nodes in the cluster using a gossip protocol to exchange information about the state of the cluster. This decentralized approach eliminates the need for a single point of failure or a coordinator node, making Cassandra highly scalable and resilient.

Magic Mouse compatibility with Late 2013 iMac

Currently using an old 'Magic Mouse' Version 1, Model No: A1296 (the one with AA Batteries) which has started to 'lose connection' with my late 2013 27 inch iMac which is running macOS Catalina Version 10.15.7.

Purchased a new 'Magic Mouse', Model No: A1657, with a view of replacing my current old Magic Mouse (A1296) as the specifications say it will work with OS X 10.11 or later which my iMac is - Version 10.15.7.

New Magic Mouse (A1657) comes with USB-C to Lightening Cable. My late 2013 iMac only has USB-A ports. To pair the new 'Magic Mouse' the supplied instructions say the following:

"To pair your mouse with your Mac, use the USB-C to Lightening Cable that came with your mouse. Plug the Lightening end into the Lightening port on the bottom of your mouse. Plug the USB-C end into a USB-C port on your Mac. Slide the on/off switch to on (so green is visible). Your mouse will pair automatically with your Mac. After the mouse is paired, disconnect the cable to use your mouse wirelessly".

So at this stage I'm unable to pair the new Magic Mouse to my iMac as previously mentioned my iMac only has USB-A ports UNLESS I now go and purchase a USB-A Cable with USB-C connector.

Has anyone else had this problem?

Am I correct in saying that I now need an additional cable to get the new mouse 'paired' with my late 2013 27 inch iMac?

if you have an iPhone and the charging cable, that will do. The mouse does not take USB-C ; its lightening connector.

Cassandra also provides tunable consistency levels, allowing developers to balance data consistency and availability based on their application's requirements. This flexible consistency model is particularly useful in scenarios where the low latency of data access is crucial, such as real-time analytics or high-traffic web applications. Another important feature of Cassandra is its support for automatic data partitioning and replication. Data in Cassandra is automatically partitioned based on the value of a partition key, ensuring that data with the same partition key is stored on the same node. Cassandra also provides configurable options for data replication, allowing developers to tune the number of replicas and their placement strategy to meet their specific needs. In addition to its distributed nature, Cassandra provides a number of other features that make it suitable for a wide range of applications. These include support for efficient data compression, in-memory caching, and integrated secondary indexes. Cassandra also has built-in support for time series data, making it an ideal choice for storing IoT sensor data or event logs. In conclusion, Cassandra is a powerful distributed database system that offers high scalability, fault tolerance, and flexible consistency models. Its support for data partitioning, replication, and other advanced features make it a popular choice for modern-day applications that deal with large volumes of data and require low-latency access..
