Cost Optimization Challenge: Managing Billing Records in Azure Serverless Architecture

We have a serverless architecture in Azure, where one of our services stores billing records in Azure Cosmos DB. The system is read-heavy, but records older than three months are rarely accessed.

Over the past few years, the database size has significantly grown, leading to increased costs. We need an efficient way to reduce costs while maintaining data availability.

Current System Constraints

Record Size: Each billing record can be as large as 300 KB.
Total Records: The database currently holds over 2 million records.

Please make fork of this, as this can be removed by Github.com sooner or later.
