Research direction

The issue provides a Python v2 function using the Azure table_input binding, along with reproduction steps and logs. Start by reproducing the binding with the shown row_key and partition_key, then trace how the table input is resolved. Done means the binding returns only the requested row and a regression check covers that behavior.

Written by the indexing model from the issue text.

Description

area:python-functions bug python python-sdk
Expected Behavior

I want to read only rows for specific row key and partition key from a table storage in azure.

Actual Behavior

The function returned all rows for the partition instead of filtering on row key.

Steps to Reproduce
  1. Create a python v2 function in vs code on mac.
  2. Specify the table as input binding with the relevant details
  3. Print the table data read
Relevant code being tried
import logging
import azure.functions as func
import json

app = func.FunctionApp()

@app.table_input(arg_name="messageJSON",
    connection="table_conn",
    table_name="lastSyncStatus",
    row_key="inspector",
    partition_key="category")
@app.timer_trigger(schedule="0 */5 * * * *", arg_name="myTimer", run_on_startup=False, use_monitor=False) 
def table_in_binding(myTimer: func.TimerRequest, messageJSON):
    message = json.loads(messageJSON)
    logging.info(message)
