We do have a couple of issues that might work for contributors new to this project.

1. Add minmax information to blocks/segments in the current datastore. This information is primarily used for data filtering. (#448)
2. Implement a bloomfilter for the blocks/segments to enhance point queries. (#467)
3. Currently, query results are stored in memory in a columnar format. However, the client expects the results in Apache Arrow format. At the moment, the format conversion is executed on the Python client, but this worsens the performance, so we plan to convert the results to Apache Arrow format on the server side before sending them to the client.
4. There are several optimizer rules to implement, such as constant folding and simplification of arithmetic expressions, which are not yet on the roadmap. Feel free to work on them if interested.
5. We have additional complicated tasks not listed here. For instance, the current executor operates with one thread per CPU. We're considering using coroutine to enhance efficiency, but we don't have a solid solution yet. If you have experience in this area, you are very welcome to propose your solution.
6. We understand you're interested in contributing C++ code. However, if that's not the case, there's also unimplemented Python code, such as test cases and the Python SDK API.
