[WIP] switch to host config

[swilly22]

#619

[coderabbitai]

Walkthrough

The recent updates to the configuration system involve a comprehensive overhaul. Enhancements include new parameters, dynamic handling of settings, and integration with RedisModule for improved management. These changes aim to boost flexibility and performance in system configurations.

Changes

Files	Change Summary
.../config.c, .../config.h	Updated to include new configuration parameters such as timeout settings, cache size, and more. Added functions for dynamic configuration management and enhanced integration with RedisModule.

🐇✨
In the warren of code, beneath the moon's glow,
A rabbit hopped through, with changes in tow.
New settings here, a tweak there, all spry,
Configs aligned, like stars in the sky.
Oh, how the servers hum, ever so bright,
With every line tuned just right!

src/configuration/config.h (14)

16-25: Ensure that the default, minimum, and maximum timeout values are consistent and logical. The default and minimum values are both set to 0, which implies no timeout. This could be intentional but warrants a double-check to ensure it aligns with the application's requirements.

---

26-31: The cache size configuration allows a minimum of 0, which effectively disables caching. If this is intended, it's fine; otherwise, consider setting a reasonable minimum value to prevent misconfigurations.

---

32-37: The thread count configuration's minimum and default values are both set to 1. Ensure this is appropriate for the application's performance and operational environment, especially in multi-threaded contexts.

---

38-44: The result set size configuration is unlimited by default, which could potentially lead to high memory usage if not properly managed. Consider whether it would be prudent to set a more conservative default value.

---

45-50: The OpenMP thread count is set to a default and minimum of 1. If the application is expected to benefit from parallel processing, consider allowing a higher default value based on the number of available CPU cores.

---

51-56: The maximum entity count per virtual key has a very high maximum limit (LLONG_MAX). Ensure that such a high limit is necessary and that the application can handle such large values without performance degradation.

---

57-63: The configuration for the maximum number of queued queries is set to unlimited by default. This could lead to resource exhaustion under high load. Consider setting a more realistic default limit.

---

64-70: The memory capacity per query/thread is unlimited by default, which might lead to excessive memory usage. It's advisable to set a sensible default to prevent potential out-of-memory issues.

---

71-76: The default number of pending changes before flushing is set to 10000. Confirm that this value is based on performance testing and aligns with the expected workload and system capabilities.

---

77-82: The node creation buffer size has a very high maximum limit. Verify that the system can handle such a buffer size and consider implications on memory usage.

---

83-88: The maximum number of info queries is capped at 5000. Ensure this limit is based on realistic usage scenarios and system testing.

---

89-94: The effects replication threshold has a maximum set to LLONG_MAX, which is extremely high. Validate that this setting is appropriate and won't cause unintended side effects in operational environments.

---

95-101: The bolt protocol port is disabled by default. Confirm that this setting aligns with the security and operational policies of the application.

---

102-112: Review the conditional compilation for the ASYNC_DELETE default value. Ensure that the settings are appropriate for both development (with memory checks) and production environments.

src/configuration/config.c (3)

33-36: The addition of async_delete and cmd_info_on boolean flags in the configuration structure is noted. Ensure that these flags are properly used throughout the application to control behavior as expected.

---

693-906: The registration of configuration parameters using RedisModule_Register*Config functions is critical. Ensure that each configuration parameter is registered with the correct default, min, and max values, and that the getters and setters are correctly implemented.

---

978-982: The configuration initialization function Config_Init includes a call to _Config_Register, which is expected. Ensure that all configurations are loaded successfully and that the default settings are correctly applied.

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.

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.

CodeRabbit Commands (invoked as PR comments)

• @coderabbitai pause to pause the reviews on a PR.
• @coderabbitai resume to resume the paused reviews.
• @coderabbitai review to trigger a review. This is useful when automatic reviews are disabled for the repository.
• @coderabbitai resolve resolve all the CodeRabbit review comments.
• @coderabbitai help to get help.

Additionally, you can add @coderabbitai ignore anywhere in the PR description to prevent this PR from being reviewed.

CodeRabbit Configration File (.coderabbit.yaml)

• You can programmatically configure CodeRabbit by adding a .coderabbit.yaml file to the root of your repository.
• Please see the configuration documentation for more information.
• If your editor has YAML language server enabled, you can add the path at the top of this file to enable auto-completion and validation: # yaml-language-server: $schema=https://coderabbit.ai/integrations/schema.v2.json
