As discussed in today's SIG meeting:

1. We need more detailed TODO items and a clearer solution description.
2. The OceanBase community project incubation process works as follows:

• first, submit a PR in the [community](https://github.com/oceanbase/community) repo requesting to create a new repository. You can use this example as a reference: add vote to create seekdb rust sdk repo community#59.
• Once the proposal receives approval from more than two-thirds of the TOC members, I’ll help create the project repo under https://github.com/ob-labs/.
