Hi All,
Since the last discussion, we have done the following based on suggestions.
1. Split flink-connector, spark-connector, and doris-mananger from the Doris
repo into three separate repo.
- https://github.com/apache/incubator-doris-manager
- https://github.com/apache/incubator-doris-flink-connector
- https://github.com/apache/incubator-doris-spark-connector
so that we can release these modules independently.
2. finished releasing both spark-connector and flink-connector components.
1. https://lists.apache.org/thread/gql1xorqs1smlq5o3jxfjgnzfh4woh2z
2. https://lists.apache.org/thread/gdhym3pv15265dlssc8knsn3bomnpmzj
3. Binary release of Doris core 1.0.0 is being voted on at IPMC.
https://lists.apache.org/thread/y2plp5gwl2cpk54jb4g2myfn91s6q7yt
I think we can continue the discussion about Doris graduation issues now.
If there are no other comments, I will start preparing the Resolution and start
a discussion at IPMC
