Hi, thank you for your contribution!

Before we move on to the PR review, could you please provide a more detailed explanation of your design? For example, for features like timeseries (#3044) and t-digest (#2542), there were corresponding proposals that helped the community better understand the data structure design and the reasoning behind it. This makes it easier for community members to review the work and reach a consensus.
