Contributor Challenges (Collection-5)

The OpenMLDB project is a community-driven project, thus we welcome all kinds of contribution from the community. We have started an OpenMLDB Contributor Program, which provides rewards to encourage you to join our community.

Here is the explanation about this program (we also provide [a Chinese version here](https://mp.weixin.qq.com/s?__biz=MzkwMDM1MjQwMw==&mid=2247485557&idx=1&sn=3570adaa4efa080e36a84e9c0815355d&chksm=c0441889f733919ff7dc6d1e74e189b73953c2d07d927ba7a3f213793bd7ebb33c7695f18c5f&scene=132#wechat_redirect ):

We have listed issues that are suitable for contributors who join the OpenMLDB community for the first time (see the below list). If you would like to contribute, please leave a message of "Please assign this task to me.". When a PR is submitted, please also link the PR to the corresponding issue.
For a successful contributor, in order to redeem your rewards (mouse pad, USB hub, OpenMLDB customized souvenir and so on), please shoot an email to [contact@openmldb.ai](mailto:contact@openmldb.ai), or join [Slack ](https://join.slack.com/t/openmldb/shared_invite/zt-ozu3llie-K~hn9Ss1GZcFW2~K_L5sMg)to contact us.
Before you start, we strongly encourage to read through our [Contribution Guideline](https://github.com/4paradigm/OpenMLDB/blob/main/CONTRIBUTING.md).

- For easy tasks (< 1 day), please refer to issues labeled with [`good first issue`](https://github.com/4paradigm/OpenMLDB/issues?q=is%3Aopen+is%3Aissue+label%3A%22good+first+issue%22)
- For tasks that require certain effort (1-3 days), please refer to issues labeled with [`call-for-contributions`](https://github.com/4paradigm/OpenMLDB/issues?q=is%3Aopen+is%3Aissue+label%3Acall-for-contributions).

This is a meta-issue directing newcomers to other issues. Read the contribution guideline at CONTRIBUTING.md, then look for issues labeled 'good first issue' or 'call-for-contributions' in the repository. Choose a specific issue from those lists to start work.
