Apache ORC (Optimized Row Columnar) is a free and open-source column-oriented data storage format of the Apache Hadoop ecosystem. It is similar to the other columnar-storage file formats available in the Hadoop ecosystem such as RCFile and Parquet. It is compatible with most of the data processing frameworks in the Hadoop environment.
In February 2013, the Optimized Row Columnar (ORC) file format was announced by Hortonworks in collaboration with Facebook. A month later, the Apache Parquet format was announced, developed by Cloudera and Twitter.
