Partitioned File Dimension Prerequisite

To write to a partitioned file dimension, Spark must be configured to allow overwriting files within a partition. When writing to unpartitioned files, no action is needed.

To enable overwriting partitions, set the spark.sql.sources.partitionOverwriteMode Spark configuration property to dynamic.

You can configure the property in Spark, or you can configure the property in individual pipelines. Configure the property in Spark when you want to enable overwriting partitions for all Transformer pipelines.

To enable overwriting partitions for an individual pipeline, add an extra Spark configuration property on the Cluster tab of the pipeline properties.
