Hello @aayush3011 and thank you for opening this pull request. Please understand that we'll need some time to review it, it's quite a number of lines of code. By the way, have you considered releasing it yourself in a separate repository? We would still list it in the overview of Haystack integrations https://haystack.deepset.ai/integrations/ but the difference would be that you keep ownership of the code.

It seems that we can already use Azure CosmosDB via our existing integrations.
See https://haystack.deepset.ai/integrations/azure-cosmos-db.

I am closing the PR for the moment.
