What are the ways in which Apache Spark handles accumulated Metadata?

Question Posted / daizy sagar


What are the ways in which Apache Spark handles accumulated Metadata?..

Answer / Vimlesh Kumar

Apache Spark handles accumulated metadata in two primary ways: Persistent Disk and Memory. For small datasets, metadata can be stored entirely in memory to minimize I/O operations. For larger datasets, Spark may spill metadata to disk if it exceeds the available memory.
