Hi, I have a PySpark DataFrame in Databricks. I included the following code multiple times during processing:

df_final.where(col('dh_state_name')=='Wisconsin').where(col('dh_place_name')=='Madison').where(col('property_type')=='Single-family').display()

These should be showing the exact same results, but sometimes it randomly says "Query returned no results". There is no consistency either; the exact same code will show different results across runs. All of the code is deterministic, so I'm confused about why this is happening. Any thoughts?

Not a delta io question
