Apache Doris is an easy-to-use, high performance and unified analytics database.

Project mention: Variant in Apache Doris 2.1.0: a new data type 8 times faster than JSON for semi-structured data analysis | dev.to | 2024-03-27

As an open-source real-time data warehouse, Apache Doris provides semi-structured data processing capabilities, and the newly-released version 2.1.0 makes a stride in this direction. Before V2.1, Apache Doris stores semi-structured data as JSON files. However, during query execution, the real-time parsing of JSON data leads to high CPU and I/O consumption in addition to high query latency, especially when the dataset is huge and complicated. Moreover, the lack of a pre-defined schema means there is no handle for query optimization.
