Hudi (pronounced Hoodie) stands for `Hadoop Upserts anD Incrementals`. Hudi manages storage of large analytical datasets on [HDFS](http://hadoop.apache.org/docs/stable/hadoop-project-dist/hadoop-hdfs/HdfsDesign.html) and serve them out via two types of tables
Apache Hudi (pronounced Hoodie) stands for `Hadoop Upserts anD Incrementals`. Hudi manages storage of large analytical datasets on DFS (Cloud stores, HDFS or any Hadoop FileSystem compatible storage) and provide ability to query them via three types of views
* **Read Optimized Table** - Provides excellent query performance via purely columnar storage (e.g. [Parquet](https://parquet.apache.org/))
* **Near-Real time Table (WIP)** - Provides queries on real-time data, using a combination of columnar & row based storage (e.g Parquet + [Avro](http://avro.apache.org/docs/current/mr.html))
* **Read Optimized View** - Provides excellent query performance via purely columnar storage (e.g. [Parquet](https://parquet.apache.org/))
* **Incremental View** - Provides a change stream with records inserted or updated after a point in time.
* **Real time View ** - Provides queries on real-time data, using a combination of columnar & row based storage (e.g Parquet + [Avro](http://avro.apache.org/docs/current/mr.html))
