Walkthrough

This update introduces a new feature for exporting database data in our CLI tool. A DatabaseData variant has been added to the ExportTarget enum, replacing the deprecated TableData. An asynchronous function, export_database_data, has been implemented to facilitate this export, and the do_work method in the Tool implementation has been updated to handle the DatabaseData target. Additionally, new fields for specifying a time range enhance the export command's functionality.

Changes

File	Change Summary
`src/cmd/src/cli/export.rs`	Added `DatabaseData` variant to `ExportTarget` enum with deprecation note for `TableData`, implemented `export_database_data` function, updated `do_work` function in `Tool` implementation to handle `DatabaseData`, and added `start_time` and `end_time` fields to `ExportCommand`.

Poem

In lines of code, new paths arise,
DatabaseData now with clear skies.
Exporting data swift and neat,
The CLI tool, a coder's treat.
Deprecated ways now bow and part,
A fresh new start, a work of art. 🐇✨

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.
