2 Distributed storage

Distributed storage is a technology that distributes data across multiple nodes or locations, rather than storing it in a single centralized location. Distributed storage can improve data availability, reliability, and performance, as it reduces the risk of data loss or corruption due to single point of failure, network congestion, or malicious attacks. Data scientists can use distributed storage to store and retrieve data faster and more reliably, especially for large-scale or complex data sets. For example, distributed file systems, such as Hadoop Distributed File System (HDFS), can store and process massive amounts of unstructured or semi-structured data in parallel, using clusters of commodity hardware. Similarly, distributed databases, such as Cassandra or MongoDB, can store and query structured or semi-structured data in a scalable and consistent manner, using replication and partitioning techniques. However, distributed storage also has some challenges, such as complexity, consistency, and security. Data scientists need to understand the design principles and trade-offs of distributed storage systems, such as the CAP theorem, and how they affect data quality and integrity.

3 In-memory storage

In-memory storage is a technology that stores data in the main memory or RAM of a computer, rather than on disk or other secondary storage devices. In-memory storage can significantly improve data performance, as it eliminates the need for disk I/O operations, which are often the bottleneck for data processing and analysis. Data scientists can use in-memory storage to store and retrieve data faster and more efficiently, especially for real-time or interactive data applications. For example, in-memory databases, such as Redis or Memcached, can store and access key-value pairs or other simple data structures in memory, providing high-speed and low-latency data operations. Similarly, in-memory computing platforms, such as Apache Spark or SAP HANA, can store and process large amounts of complex data in memory, using distributed and parallel computing techniques. However, in-memory storage also has some limitations, such as volatility, capacity, and cost. Data scientists need to consider the trade-offs between in-memory storage and other options, depending on their data requirements and resources.
