What is Amazon Redshift?
Amazon Redshift is a data warehouse service provided by Amazon Web Services (AWS) that can process petabytes of data. It is designed for large-scale data storage, analysis, and querying of structured data for various purposes. Amazon Redshift does not need any configurations to analyze or store data.
Features of Amazon Redshift
Here are some primary features of Amazon Redshift which make it unique:
Massive Parallel Processing (MPP): Amazon Redshift employs an MPP architecture that can manage massive volumes of data, distributing queries across the multiple nodes in a cluster. Due to this parallel functioning mechanism, Amazon Redshift enables high-performance query execution and analytics.
Columnar storage: Instead of storing data in rows, Amazon Redshift stores data in columns, making data compression efficient and query performance faster. Also, by storing data in columns, I/O operations are reduced as only the column needed for the query is read.
SQL-based interface: Amazon Redshift supports standard SQL queries, making the service familiar and easily-operatable for the users. We can work with a wide range of SQL functionalities and analytics functions on Amazon Redshift.
Amazon Redshift architecture
Amazon Redshift cluster consists of two types of nodes: leader and compute. It has multiple compute nodes, and the leader node distributes tasks among them. The compute nodes in Amazon Redshift have their own CPU and storage, making processing and querying more efficient.
Once the tasks are completed, the compute nodes pass the results to leader node, and the leader node sends the combined result of jobs to the user making the query. The entire hierarchy divides queries into smaller jobs, hence decreasing the processing time and increasing efficiency.
Why Amazon Redshift?
Amazon Redshift lets businesses store and access their data without getting into the hassle of a provisioned data warehouse. As organizations highly rely on data-driven insights for their decision-making processes, the need for high-performance data warehousing solutions becomes necessary. Amazon addresses this need by providing a scalable and cost-effective solution, Amazon Redshift. Its capabilities enable fast query processing, its integration with other AWS services, cost-effectiveness, and high performance.
