A data engineering team is running a nightly job that processes a large Delta table. The job is taking longer than expected, and the team suspects the cluster is under-provisioned. They want to improve performance without changing the job's code. Which action should they take?

Disable Unity Catalog for the table

Increase the cluster's node size or add more workers

Use Delta Lake time travel to query an older version

Change the job's schedule to run less frequently

A data engineering team is designing a data lake on Databricks. They need to ensure that concurrent writes to the same table do not corrupt data and that each write is recorded as a version. Which technology should they use as the table format?

JSON files with a custom locking mechanism

CSV files stored in cloud storage

Parquet files managed by a traditional Hive metastore
