Data storage

A Cosmos DB analytical store is fully isolated from transactional workloads. The operational data in a Cosmos DB container is internally stored in row-based transactional stores in order to allow fast transactional reads and writes.

It is not recommended to run complex queries on your transactional workload – it may cause bad performance for your application running these queries. Ideally, you should add an analytical data layer on top of Cosmos DB transactional data if you want to perform complex operations on the data. The major caveat for this architecture is an ETL operation for data sync between transactional and analytical data stores. This additional step may lead to increased Total Cost of Operation (TCO) and overhead of maintaining the data in sync always.

With this new feature of Synapse Link, Cosmos DB gives you the flexibility to enable an analytical store within your Cosmos DB account without performing an ETL operation. Both the data layers are...
