Doris is an MPP-based interactive SQL data warehousing for reporting and analysis. Its original name was Palo, developed in Baidu. After donated to Apache Software Foundation, it was renamed Doris.
Doris mainly integrates the technology of Google Mesa and Apache Impala, and it is based on a column-oriented storage engine and can communicate by MySQL client.
Doris not only provides high concurrent low latency point query performance, but also provides high throughput queries of ad-hoc analysis.
Doris not only provides batch data loading, but also provides near real-time mini-batch data loading.
Doris also provides high availability, reliability, fault tolerance, and scalability.
The simplicity (of developing, deploying and using) and meeting many data serving requirements in single system are the main features of Doris (refer to Overview).
