Apache Hudi (Incubating)

Apache Hudi (Incubating) (pronounced Hoodie) stands for Hadoop Upserts Deletes and Incrementals. Hudi manages the storage of large analytical datasets on DFS (Cloud stores, HDFS or any Hadoop FileSystem compatible storage).

Features

Upsert support with fast, pluggable indexing
Atomically publish data with rollback support
Snapshot isolation between writer & queries
Savepoints for data recovery
Manages file sizes, layout using statistics
Async compaction of row & columnar data
Timeline metadata to track lineage

Hudi provides the ability to query via three types of views:

Read Optimized View - Provides excellent snapshot query performance via purely columnar storage (e.g. Parquet).
Incremental View - Provides a change stream with records inserted or updated after a point in time.
Real-time View - Provides snapshot queries on real-time data, using a combination of columnar & row-based storage (e.g Parquet + Avro).
