Highlights

This week is China’s National Day. I wish you all a happy National Day. Openmldb-related code modifications and pull-Request are less than the same period, but there are still important Bugfixes. Including the OpenMLDB Batch module can now enable window parallel optimization and window skew optimization at the same time, while fixing the SQL optimization process repeatedly optimizing child nodes found during integration testing. This week, additional external developers participated in the Gitee reward Issue, fixed the C++ header style reconstruction problem, please refer to [reward] for more reward tasks, the first phase of the fourth paradigm reward program is coming… .

More developers are welcome to pay attention to and participate in OpenMLDB open source projects.
