# Hudi
|
|
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 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))
