Azure Cosmos DB is a SLA-based system that provides unlimited SCALE, with GUARANTEES for latency, throughput, availability, and consistency. It's Cassandra API too allows unlimited storage of data. This unlimited storage is based on horizontal scaleout of data using partitioning as the key concept. The partitioning concept is well explained in the Partition and scale in Azure Cosmos DB article.

The 10-GB LIMIT on the NUMBER of entities or items per logical partition you should ADHERE to. To ensure that your application scales well, we recommend that you not create a hot partition by storing all information in one partition and querying it. This error can only come if you data is skewed - that is you have lot of data for one partition key - i.e., more than 10 GB. You can find the distribution of data using the storage portal. Way to fix this error is to recreate the table and choose a granular primary (partition key), which allows better distribution of data.
