Once you have crawled Microsoft Azure Cosmos DB, you can use connector-specific filters for quick asset discovery. The following filters are currently supported for Microsoft Azure Cosmos DB assets:
-
Accounts — you can use the following filters:
- Account Type — filter accounts by account type
- Subscription ID — filter accounts by subscription ID
- Account Resource Group — filter accounts by resource group
- Collections — Type filter, filtering options include Time Series, Capped, and Clustered collection types
Atlan crawls and maps the following assets and properties from Microsoft Azure Cosmos DB. Atlan currently does not support lineage for Microsoft Azure Cosmos DB assets.

Columns
To extract columns from Microsoft Azure Cosmos DB collections, Atlan analyzes document schemas, which must be enabled and configured to crawl columns.
Atlan consolidates multiple document schemas into a unified view, capturing all possible fields with their nesting levels and data types. The system then performs a depth-first traversal, converting each unique field path into column entries while tracking parent-child relationships and hierarchy through qualified names. The total column count is calculated by summing up all unique paths, including nested structures, with arrays processed to identify additional column patterns.
Atlan maps the following metadata from Microsoft Azure Cosmos DB to its Column asset type.
- Atlan supports nested columns up to level 35 for parent columns.
- Column-level lineage is currently not supported.
- Tag propagation is supported from:
- collections to columns
- parent to nested columns
