Confusion about CosmosDB binding and retries

I am currently trying to use the retry policy in the CosmosDB binding in the Function. However, I think that the docs are bit misleading as of now and I am unsure whether the retry policy will work or not.

Repro steps

Provide the steps required to reproduce the problem

1. I have a python Function that uses the CosmosDB binding. I wanted also to add retry policy as stated here: https://learn.microsoft.com/en-us/azure/azure-functions/functions-bindings-error-pages?tabs=fixed-delay%2Cin-process&pivots=programming-language-python#retries The definition of the function.json looks like this:

{
  "scriptFile": "../src/handler.py",
  "entryPoint": "handle",
  "bindings": [
    {
      "type": "cosmosDBTrigger",
      "name": "documents",
      "direction": "in",
      "connectionStringSetting": "CosmosDB_Endpoint",
      "databaseName": "database",
      "collectionName": "collection",
      "CreateLeaseCollectionIfNotExists": true
    }],
    "retry": {
      "strategy": "exponentialBackoff",
      "maxRetryCount": 3,
      "minimumInterval": "00:01:00",
      "maximumInterval": "00:15:00"
    }
}

1. When the host is initializing is is showing the following log:

Expected behavior

Based on the information found on the https://learn.microsoft.com/en-us/azure/azure-functions/functions-bindings-error-pages?tabs=fixed-delay%2Cin-process&pivots=programming-language-python#retries it seems that the retry policy is supported for the CosmosDB binding. I was expecting that this kind of log won’t be shown.

Actual behavior

The log regarding the support of the retry policy is showing which is somewhat confusing in relation to the documents.

Okay, I posted a issue on the azure-docs github repository so that the documentation is clearer about this (https://github.com/MicrosoftDocs/azure-docs/issues/106040). Closing this ticket

@Ceglowa The documentation page has a Feedback section at the bottom, please use that to report documentation related issues. I understand what you are describing, but there is nothing that can be changed on this repo to either update the documentation or to handle Bundle related questions.
