Walkthrough

The changes in this pull request focus on enhancing error handling and logging across several classes in the airqo_etl_utils module. The AirQoApi class now includes improved error handling in the get_devices and get_meta_data methods. The DataValidationUtils class replaces print statements with logging calls and adds checks for empty DataFrames. The MessageBrokerUtils class modifies the consume_from_topic method to support streaming and improves error handling during message consumption. Overall, these modifications aim to increase the robustness and maintainability of the code.

274-274: Good improvement in exception handling!

The use of logger.exception is excellent as it automatically includes the stack trace. However, the error message could be more specific.

Consider enhancing the error message to include the row data being processed:

-logger.exception(f"Error ocurred: {ex}")
+logger.exception(f"Error processing row data: {ex}")

316-317: Minor: Simplify the warning message

The f-string is used without any placeholders, which is unnecessary.

-logger.warning(f"No devices returned.")
+logger.warning("No devices returned.")

317-317: f-string without any placeholders

Remove extraneous f prefix

Line range hint 1-317: Consider enhancing type safety and input validation

The code would benefit from:

  1. Adding return type hints to methods
  2. Adding input validation for critical parameters
  3. Adding docstrings to document the expected data formats

For example:

def fill_missing_columns(
    data: pd.DataFrame,
    cols: list[str]  # More specific type hint
) -> pd.DataFrame:
    """
    Fill missing columns in the DataFrame with None values.
    
    Args:
        data: Input DataFrame to process
        cols: List of column names to check and fill
        
    Returns:
        DataFrame with missing columns added
    
    Raises:
        ValueError: If data is None or empty
    """
    if data is None or data.empty:
        raise ValueError("Input DataFrame cannot be None or empty")
    # ... rest of the implementation

Would you like me to provide more examples of type hints and input validation for other methods?

190-191: Consider adding more context to the error log

The error message could be more informative by including the request parameters.

-            logger.exception(f"Failed to fetch devices: {e}")
+            logger.exception(f"Failed to fetch devices with params={params}: {e}")

Line range hint 4-16: Consider grouping related imports

The imports could be better organized by grouping standard library imports, third-party imports, and local imports.

+ # Standard library imports
import traceback
from urllib.parse import urlencode
from typing import List, Dict, Any, Union, Generator, Tuple

+ # Third-party imports
import pandas as pd
import simplejson
import urllib3
from urllib3.util.retry import Retry
import logging

+ # Local imports
from .config import configuration
from .constants import DeviceCategory, Tenant
from .utils import Utils

logger = logging.getLogger(__name__)

Line range hint 71-73: Fix incomplete exception logging in calibrate_data method

The logger.exception() call is missing the error message parameter.

-            logger.exception()
+            logger.exception(f"Failed to calibrate data: {ex}")

Line range hint 391-392: Fix incomplete exception logging in get_meta_data method

Similar to the previous issue, the exception logging is incomplete.

-                logger.exception()
+                logger.exception(f"Failed to fetch meta data for endpoint {endpoint}: {ex}")

Line range hint 654-698: Consider implementing request timeout

The __request method should include a timeout parameter to prevent hanging requests.

     retry_strategy = Retry(
         total=5,
         backoff_factor=5,
     )

-    http = urllib3.PoolManager(retries=retry_strategy)
+    http = urllib3.PoolManager(retries=retry_strategy, timeout=urllib3.Timeout(connect=5.0, read=30.0))

Line range hint 654-698: Consider implementing request rate limiting

The __request method could benefit from rate limiting to prevent overwhelming the API server.

Consider implementing a rate limiter using a token bucket algorithm or similar approach. This would help prevent API rate limit errors and ensure good API citizenship.


TODO comments require attention beyond just documentation

The review comment focused on documentation TODOs, but the analysis reveals a broader scope of concerns:

  • 4 methods lack docstring documentation: calibrate_data, refresh_airqloud, refresh_grid, and update_sites
  • 3 methods have functionality verification TODOs: get_favorites, get_location_history, and get_search_history
  • 3 implementation-related TODOs:
    • Bulk API posting limitation investigation
    • Data filtering efficiency concern in measurements endpoint
    • Resource creation investigation in request handling

These TODOs indicate both documentation gaps and potential implementation issues that should be addressed for code quality and reliability.

🔗 Analysis chain

Line range hint 401-402: Address TODO comments regarding documentation

Several methods have TODO comments indicating missing or outdated documentation. This should be addressed to maintain code quality.

Would you like me to help generate the missing documentation for these methods?

Also applies to: 417-418, 432-433


Let me search specifically for TODO comments in the file mentioned in the review.


Let me check the context around these TODO comments to better understand their scope and impact.

124-124: Great improvement in error reporting!

The switch from print to logger.warning is a good practice for better observability and consistent error handling. The warning level is appropriate for missing columns as it's not a critical error but something that should be noted.


306-315: Well-structured data validation flow!

The empty DataFrame check before processing is a good defensive programming practice. The checksum logic is properly nested to avoid unnecessary computations.

src/workflows/airqo_etl_utils/airqo_api.py (2)

188-193: Improved error handling in get_devices method looks good!

The addition of try-except block with proper error logging enhances the robustness of the API client.


Line range hint 654-698: Verify error handling for all HTTP status codes

The current error handling only checks for 200 and 201 status codes. Other success (2xx) or redirect (3xx) codes might need handling.

#!/bin/bash
# Search for all HTTP status code handling in the codebase
rg -n "response.status.*[23]\d{2}" src/workflows/airqo_etl_utils/
