- Although Redshift is mostly Postgres-compatible, its SQL dialect and performance profile are different.
- Redshift supports only [12 primitive data types](https://docs.aws.amazon.com/redshift/latest/dg/c_Supported_data_types.html). ([List of unsupported Postgres types](https://docs.aws.amazon.com/redshift/latest/dg/c_unsupported-postgresql-datatypes.html)\)
- It has a leader node and computation nodes (the leader node distributes queries to the computation ones). Note that some functions [can be executed only on the lead node.](https://docs.aws.amazon.com/redshift/latest/dg/c_SQL_functions_leader_node_only.html)
- 🔹Make sure to create a new [cluster parameter group](http://docs.aws.amazon.com/redshift/latest/mgmt/working-with-parameter-groups.html) and option group for your database since the default parameter group does not allow dynamic configuration changes.
- Major third-party BI tools support Redshift integration (see [Quora](https://www.quora.com/Which-BI-visualisation-solution-goes-best-with-Redshift)).
- [Top 10 Performance Tuning Techniques for Amazon Redshift](https://blogs.aws.amazon.com/bigdata/post/Tx31034QG0G3ED1/Top-10-Performance-Tuning-Techniques-for-Amazon-Redshift) provides an excellent list of performance tuning techniques.
- [Amazon Redshift Utils](https://github.com/awslabs/amazon-redshift-utils) contains useful utilities, scripts and views to simplify Redshift ops.
