![]() Horizontal scaling will not require more servers as it is done with the help of compute nodes so that the scaling can be done at a low cost. This expansion of nodes helps to create more clusters. Scaling is easy in RedShift as AWS helps to manage node configuration and scale horizontally with parallel processing. Vertical scaling is done with PostgreSQL which is costly. Scaling can be done only by creating a new server for the data or copying the entire data into a separate database. Scaling is not easy in PostgreSQL as the compute nodes are not present in this database. Storage efficiency is increased here as compression of data happens in the column level since each column carries similar data. This helps to read data faster and return the queries more efficiently than PostgreSQL. ![]() This helps to build queries around the rows inserted and also we can manage the tables in the way the data got inserted into the tables.ĭata is inserted in the form of columns. Let’s discuss the top comparison between PostgreSQL vs RedShift: PostgreSQLĭata is stored and managed in rows that helps in creating tables directly. We do not have any leader node or worker nodes in PostgreSQL as it works with a single node database.Ĭomparison Table of PostgreSQL vs RedShift Work is distributed among different worker nodes and the data is managed well so that it can be queried whenever needed. A leader node is present in the database cluster so that it manages the data insertion and management into the database.PostgreSQL helps to get back the space in the database with the VACUUM command whereas RedShift sorts all rows as well along with reclaiming space in the database. The use of VACUUM is different in both databases. ![]() No distribution styles or patterns are followed in PostgreSQL where we must locate similar data-carrying columns with queries. This helps users to locate the data easily. The values are compared with other columns and if there are matching values, the columns are placed together. We have key distribution in RedShift where the data is crosschecked with the key values in the column and placed in the same columns. Different distribution styles are followed in RedShift so that the data is inserted faster into the database.We can insert and delete tables along with ‘WITH’ clause in PostgreSQL. With Create command, we can create tables along with sorting, inheritance and partitioning in PostgreSQL. We can do insert and update the table but it does not allow us to create new tables along with the insert command. We can do the distributions and sort algorithms in RedShift with the help of CREATE TABLE but inheritance and partitioning are not supported in RedShift. SQL is used in both RedShift and PostgreSQL but the application of SQL commands differ.Performance for analytics is best in RedShift than PostgreSQL. We have indexes, a foreign key concept in PostgreSQL. The data is stored in nodes and there are no clusters here. ![]() PostgreSQL is suitable for simple queries and less data. Cluster is used here so that we can manage billions of records in a single short. Foreign keys or any other constraints are not present and hence it will take time to sort out the values in RedShift database. Index keys are not used in RedShift which is replaced by SORT and DIST keys.
