Data consumed and generated by Oracle Big Data Cloud is stored in Oracle Cloud Infrastructure Object Storage, the persistent data lake for the service.
Persistent data is stored in Oracle Cloud Infrastructure Object Storage containers that were associated with clusters when the clusters were created. You can also upload data into HDFS, but that data is lost once a cluster is terminated. Log files and output data are also stored in Oracle Cloud Infrastructure Object Storage containers.
Big Data Cloud also includes the Oracle Big Data File System (BDFS), an in-memory caching layer that enables Spark jobs to run much faster.
