Hadoop Datasets: These are created from external data sources like the Hadoop Distributed File System (HDFS) , HBase, or any storage system supported by Hadoop. RDDs provide fault tolerance by tracking the lineage of transformations to recompute lost data automatically. a list or array) in your program.

Flume is mainly used for collecting and aggregating large amounts of log data from multiple sources to a centralized data location. Specifically designed for Hadoop. Tool to collect log data from distributed web servers. Quotas are byte-rate thresholds that are defined per client-id. Easy to scale.

On top of that, it’s a part of the Hadoop platform, which created additional work that we otherwise would not have had to do. RocksDB is a storage engine with a key/value interface, where keys and values are arbitrary byte streams written as a C++ library. That wraps up May’s Data Engineering Annotated.
