Each schema in a database contains tables and other kinds of named objects. If you have more additional databases inside a cluster, you should create a Hackolade model per database.Ī database contains one or more named schemas. While it is possible to create multiple databases in a single cluster, a Hackolade model corresponds to a single Redshift cluster/database. The console implies that only a single database can be created per cluster. Within a cluster, the console prompts for the creation of a database. Each cluster has a leader node and one or more compute nodes, the configuration of which should be done through the Redshift console. The data model in the picture below results from the data modeling of the sample TICKIT data:Īn Amazon Redshift cluster consists of nodes. The application closely follows the Redshift terminology and storage structure. The reverse-engineering function, if it detects JSON documents in a column with the SUPER data type, will sample records and infer the schema to supplement the DDL table definitions.

In particular, Hackolade has the unique ability to model complex semi-structured objects stored in columns of the SUPER data type.

Hackolade was specially adapted to support the data modeling of Redshift, including schemas, tables and views, plus the generation of DDL Create Table syntax. To perform data modeling for Redshift with Hackolade, you must first download the Redshift plugin.

Redshift doesn't enforce primary key, foreign key, or uniqueness constraints, although primary keys and foreign keys are used as planning hints and they should be declared if ETL process or some other process in applications to enforce their integrity. Instead, each table has a sort key, which determines how rows are ordered when the data is loaded. Amazon Redshift does not support tablespaces, table partitioning, inheritance, and certain constraints. Amazon Redshift is specifically designed for online analytic processing (OLAP) and business intelligence (BI) applications, which require complex queries against large datasets. When data is loaded into a Redshift table, Redshift distributes the rows of the table across nodes according to the table's distribution style.Īmazon Redshift is based on PostgreSQL, but they have a number of very important differences. Redshift is a columnar database better suited for analytics, and thus a more appropriate platform for a data warehouse. It is built on top of technology from massive parallel processing (MPP) to handle large scale data sets and database migrations.
