When we execute the above notebook with the parameters below: We see that the table is created successfully: Now that we have our Delta table created, we return to Databricks, where we’ll leverage Spark Structured Streaming to ingest and process the events, and finally write them to the above Delta table. Later you pass this parameter to the Databricks Notebook Activity. libraries to use in the job, as well as pre-defined parameters. Unlike ETL solutions, which replicate data, data … sys.path.insert ( 0, 'dbfs:/FileStore/code/' ) import conn_config as Connect. What is the parameter value?
