When to enable chunk skipping

You can enable chunk skipping on as many columns as you need. However, best practice is to enable it on columns that are both:

• Correlated, that is, related to the partitioning column in some way.
• Referenced in the WHERE clauses of the queries.

In the satellite example, the time of adding data to a database inevitably follows the time of gathering. Sequential IDs and the creation timestamp for both entities also increase synchronously. This means those two columns are correlated.
