doris VS ZK

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.

Apache Doris is a real-time data warehouse.

As you can imagine, a long and complicated data pipeline is high-maintenance and detrimental to development efficiency. Moreover, they are not capable of ad-hoc queries. So as an upgrade to our data warehouse, we replaced most of these components with Apache Doris, a unified analytic database.

The key to Architecture 3.0 is the combination of Flink and Doris, so this is how to connect them. Probably the most important code in building architecture 3. flink-demo stream-load-demo

https://github.com/apache/doris Is a great example. Same for it's cousin https://github.com/StarRocks/starrocks that was an early fork of the doris project.

To be fair, these are the only examples I can think of and I only learned of these as I'm standing up new data infra using starrocks.

We optimized Apache Doris to solve these problems. (Pull Request on Github)

So, in Storage Architecture 2.0, we introduced Apache Doris and Apache Spark. The whole data pipeline was a Y-shaped diagram.

The ZK framework was started by Chinese developers: https://www.zkoss.org/

Here I am taking Keikai spreadsheet and a ZK drawer component as an example demonstrating how this can be done. In this example, we will add a slide-in/out Help panel to our spreadsheet where we can display large blocks of Help text in a much more easy-to-read format.
