Hi, I am not able to find the study materials and practice questions online. @DataBricksHelp232 please let us know if it's available online. Please share the links.
Adding some more points to @karthik p 's answer.Use kryo serializer instead of java serializer.Use an optimised garbage collector such as G1GC.Use partitioning wisely on a field.
As of now we don't have any practice exams available online. We have an advance data engineering course available on academy.https://customer-academy.databricks.com/learn/course/874/advanced-data-engineering-with-databricks
I have found a course on academy page which might be helpful. But unless some practice questions are available it's challenging to clear the test.Here's the link for the course.https://customer-academy.databricks.com/learn/course/874/advanced-data-en...
