I'm using the Redshift data source to load data into spark SQL data frames. However, I'm not seeing predicate push down for my queries ran on Redshift - is that expected?
The Spark driver for Redshift pushes the following operators down into Redshift:
Filter
Project
Sort
Limit
Aggregation
Join
However, it does not support expressions operating on dates and timestamps today. If you have a similar requirement, please add a feature request via https://docs.databricks.com/resources/ideas.html
