I have used relational database with Log4Net to log message using Log4Net Configuration.
I am not sure how to configure and use Document Db ?
You can wrap your log messages as JSON documents and persist. You can use any of the SDK's available in .NET, Java, Node.js or Python or there are REST API's available to perform CRUD operations in DocDB.

I want to use Firebase Remote Config API via REST in a mobile app. Due to technical limitations, I can't use the Android/iOS SDK so I have to resort to the REST API.
However, that API requires authentication using a private key -- obviously I can't include that key in the application.
I don't need any other Firebase service at this time, just the remote config.
How can I work around this limitation? I tried following the guide at https://firebase.google.com/docs/remote-config/use-config-rest, but as mentioned it requires to first generate a short-lived OAuth2 token using the auth API.
According to the documentation on using the Remote Config REST API:
This document describes how you can use the Remote Config REST API to read and modify the set of JSON-formatted parameters and conditions known as the Remote Config template.
So the REST API is for modifying Remote Config variables, the type of action you could also do in the Firebase console. It is not for use in regular clients, which consume the configuration variables. For that you'll have to use one of the provided clients, as there is no REST API and the wire protocol is not documented.
I have a .NET Core 3 Web API that has some external dependencies like Azure SignalR and Azure CosmosDb. I have create a Monitoring Controller which I want to check if the service is healthy by for example pinging those two dependencies.
I haven't found any documentation about how to do this. I know that for example, for Table Storage I can call a method "If table exists" so if it returns true, I know the service can communicate with that dependency.
There is a way to call those dependencies?
PS: I don't want to use 3rd party packages to perform this, I want to know if those services provide this kind of methods.

If you'd like to achieve same for Azure SignalR and Azure CosmosDb, you can try:
1) To check Azure SignalR service, can use management API to get details of Azure SignalR service.
2) To check Azure CosmosDb, can use this API to check if the database you want is existing.
I created Azure CosmosDb database and container for my documents.
I use NiFi as a main data ingestion tool and want to feed my container with documents from NiFi flow files.
Can anybody please share a way to post flowfile content to Azure Cosmos Db from NiFi?
Thanks in advance
UPDATE(2019.05.26):
In the end I used Python script and called it from NiFi to post messages. I passed a message as a parameter. The reason I chose python is because it has some examples on official Microsoft site with all the required connection settings and libraries, so it was easy to connect to Cosmos.
I tried Mongo component, but couldn't connect to Azure (security config didn't work), didn't really go too far with it as Python script worked just fine.
Azure CosmosDB exposes MongoDB API so you can use the following MongoDB processors which are available in NiFi to read/query/write to & from Azure CosmosDB using Apache NiFi.
DeleteMongo
GetMongo
PutMongo
PutMongoRecord
RunMonogAggregation

Valeria. According to the components list supported by Apache Nifi related to Azure, you could only get Azure Blob Storage, Queue Storage, Event Hub etc,not including Cosmos DB.
So,I suggest you using PutAzureBlobStorage to feed azure blob container with documents from NiFi flow files. Then please create a copy activity pipeline in Azure Data Factory to transfer data from Azure Blob Storage into Azure Cosmos DB.
Hello and I am new to developing with Qt for cross platform development. My current goal is to be able to cache data from a CosmosDB with my app that I've developed in Qt. I've had no problem setting up the CosmosDB, but I am confused at what the best way to communicate with the database is.
Do I need to create my own API to talk with the database? Are there libraries out there already do what I want?
You can use either standard HTTP requests, or use SQL API.
Azure Cosmos DB exposes resources through the REST APIs that can be called by HTTP/HTTPS requests. How can I develop apps with the SQL API
Azure Cosmos DB REST API reference
Also Azure Cosmos DB offers a query language as an interface to query JSON documents. The language supports a subset of ANSI SQL grammar and adds deep integration of JavaScript object, arrays, object construction, and function invocation. Microsoft shows exmaples here

The SQL Azure OData Service is a sample WCF Data Service built on top
of a SQL Azure (or SQL Server) database using Entity Framework 4.1
Code First.
The current version of this service only supports Read operations and,
in addition to exposing the SQL Azure database as an OData feed, it
adds a security layer to manage authentication / authorization.
so does it mean the my windows phone app will only be able to read from sql azure and not write to ? or can i do it by creating a data service on the asp.net server ?
i'm a little confused.
What this is saying is that the sample OData service that they provided only implements read operations. If you want read and write, you're going to have to roll that yourself.
