databricks-synthetic-data-generation

You can generate synthetic data for Databricks by creating a Python script that uses Faker, NumPy, and Spark to produce realistic patterns with non-linear distributions, then saves the output as Parquet files in Databricks volumes.

Yes, you can maintain referential integrity across synthetic datasets. The generation process creates related entities like customers, orders, and tickets with consistent keys, making them suitable for unit and integration testing in Spark.

Yes, synthetic data generation with Faker supports configurable data volumes and date ranges. You can specify parameters like the last six months of data to support pipeline benchmarking and testing scenarios.

The best way to create privacy-preserving testing datasets for Databricks is to generate synthetic data using Faker to mimic real customer patterns without exposing actual data, then save it as Parquet using Spark.

You can save synthetic data as Parquet files in Databricks volumes by running a Python script on a Databricks cluster that utilizes Spark-based persistence to write the generated datasets directly to the storage volume.

While synthetic data mimics real customer data using non-linear distributions and holidays, its limitation is that it is synthetic; it cannot capture unpredictable real-world anomalies for data science experimentation in Spark.
