What is a Databricks Temp View?
A Temp View in Databricks is essentially a temporary table-like structure that holds the results of a SQL query. Unlike permanent tables, Temp Views do not require extensive storage and are perfect for short-term data analysis within a session. Once the session is terminated, the Temp View is discarded.
How to Create a Databricks Temp View
- Start by writing your Spark DataFrame code.
- Use the
.createOrReplaceTempView("view_name")method to convert your DataFrame to a Temp View. - Execute SQL queries against this Temp View using SQL syntax.
Benefits of Using Databricks Temp View
