Hevo is fully managed and completely automates the process of not only loading data from your desired source but also enriching the data and transforming it into an analysis-ready format without having to write a single line of code. Hevo Data, a No-code Data Pipeline, helps you directly transfer data from 100+ data sources to Data Warehouses, BI tools, or a destination of your choice in a completely hassle-free & automated manner. And the number of slices per node depends on the node’s size. Each slice has its own allocated share of the node’s memory and disk share. Node Slice: A group of slices makes a node slice, making it the logical partition of a disk. The user can select from various node types, providing an optimum experience based on the user’s computation, storage, and business requirements. It performs computational work in a cluster. Each compute node has its CPU and attached disk storage defined. It resolves, develops, and executes database operations necessary to obtain results - for multiple, complex-in-nature queries.Ĭompute Node: A compute node consists of multiple node slices. Leader Node: The leader node communicates with the client application and the compute nodes. The Data warehouse cluster has a leader node, compute node, and node slices - these are the core infrastructure components of Redshift’s architecture.

These two communicate using the industry-standard JDBC and ODBC drivers for PostgreSQL.

About Redshift Indexes: DISTKEY, SORTKEY, & Column Compression EncodingĪmazon Redshift architecture is based on an extensive communication channel network between the client application and the data warehouse clusters.

And then, we will talk about recommended Redshift Indexes and the best practices for their usage. In this article, we will talk about the basics of Redshift Architecture because the concept keeps on repeating. Nonetheless, if you are confident, create the unique key constraint such that the database engine can execute queries for the same. For example, do not create the unique key constraint if you are not sure the table’s product name is not unique. It’s recommended to use primary and foreign key indexes in the data loading process - the ETL process - as hints to protect their integrity. In Redshift, a user chooses between the primary and foreign key Redshift indexes - DISKEY, SORTKEY, and Column Compression Encoding - which are amongst the best-recommended practices.
