The documentation highlights real-time insights from Edge to Cloud, enhanced Prometheus compatibility, and serverless scalability with GreptimeCloud. Optimizations include a columnar layout for time-series data, a distributed cluster architecture, flexible indexing, and support for various database protocols and APIs.

Poem

In the land of data vast and wide,
GreptimeDB now takes stride.
Metrics, Events, and Logs in one,
Real-time insights under the sun.
From Edge to Cloud, it scales so grand,
With Prometheus at its hand.
A rabbit's joy, a data tale,
In every byte, it shall prevail.

Tips

Chat

There are 3 ways to chat with CodeRabbit:

• Review comments: Directly reply to a review comment made by CodeRabbit. Example:
  • I pushed a fix in commit <commit_id>.
  • Generate unit testing code for this file.
  • Open a follow-up GitHub issue for this discussion.
• Files and specific lines of code (under the "Files changed" tab): Tag @coderabbitai in a new review comment at the desired location with your query. Examples:
  • @coderabbitai generate unit testing code for this file.
  • @coderabbitai modularize this function.
• PR comments: Tag @coderabbitai in a new PR comment to ask questions about the PR branch. For the best results, please provide a very specific query, as very limited context is provided in this mode. Examples:
  • @coderabbitai generate interesting stats about this repository and render them as a table.
  • @coderabbitai show all the console.log statements in this repository.
  • @coderabbitai read src/utils.ts and generate unit testing code.
  • @coderabbitai read the files in the src/scheduler package and generate a class diagram using mermaid and a README in the markdown format.
  • @coderabbitai help me debug CodeRabbit configuration file.

Note: Be mindful of the bot's finite context window. It's strongly recommended to break down tasks such as reading entire modules into smaller chunks. For a focused discussion, use review comments to chat about specific files and their changes, instead of using the PR comments.
