Walkthrough

This update introduces two new integer configuration properties in the environment schema for real-time streaming: one for the maximum stream length and another for the TTL. The real-time stream service now uses these environment variables instead of hardcoded values, and it consolidates stream commands (xadd and expire) into a single Redis pipeline operation.

Changes

File Path	Change Summary
apps/webapp/.../env.server.ts	Added two properties to EnvironmentSchema: REALTIME_STREAM_MAX_LENGTH (default: 1000) and REALTIME_STREAM_TTL (default: 86400 seconds).
apps/webapp/.../redisRealtimeStreams.server.ts	Replaced hardcoded stream limits with environment variables; updated Redis operations to pipeline xadd and expire commands using the new TTL setting.

Poem

I'm a rabbit in the codefield hopping,
New stream limits have got my tail a-twitching.
Configs now dance with a graceful flow,
Redis and env vars in a pipelined show.
Carrots and code—oh what a refreshing glow! 🥕✨

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>, please review it.
  • 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 gather interesting stats about this repository and render them as a table. Additionally, render a pie chart showing the language distribution in the codebase.
  • @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.
