Why teams connect Azure Cosmos DB and Box

Keep Azure Cosmos DB and Box in step: a row in Azure Cosmos DB for every file in Box, with names, paths, metadata, and status staying consistent in real time, in both directions.

A database holds structured records; a storage system holds the files those records depend on, such as contracts, images, exports, uploads, and documents. The two describe the same things from opposite sides: a row in Azure Cosmos DB says a file exists and carries its name, location, and status, while Box holds the bytes. Linked only by a hand-kept path or a one-off script, the two drift the moment a file is renamed, moved, or deleted and the record still points at where it used to be.

Stacksync syncs Change feed entries, Stored procedures and triggers, Databases, Containers in Azure Cosmos DB with Tasks, Events, Files, Folders in Box bi-directionally and in real time. File attributes, including name, path or object key, size, type, modified time, owner, and tags or custom properties, map field by field to columns on the matching row, and a change on either side shows up on the other within seconds. New files appear as rows, metadata edits travel in the direction you choose, and deletes stay consistent, with conflict rules you set in place of nightly reconciliation scripts.

Common use cases

  • 01 Sync CRM or ERP records into a Cosmos DB container that backs a customer-facing application.
  • 02 Mirror Cosmos DB items into Postgres so teams can query operational data with standard SQL.
  • 03 Two-way sync of Files and Folders between Box and an operational database so applications track document status without calling the Box API directly.
  • 04 Mirror Metadata template instances on Files into database columns so contracts and assets are searchable and reportable alongside other business data.

Common sync patterns

File metadata kept in step

Tags, custom properties, owner, or status columns edited on a row in Azure Cosmos DB write back to the matching file's metadata in Box, and metadata changed in Box updates the row, so the two never disagree about a file.

Records that point at documents

Where a record in Azure Cosmos DB references a file in Box, such as a contract, an image, an export, or an upload, the reference, path, and status stay consistent as files are renamed, moved, or replaced, so stored links keep resolving.

A landing zone for incoming files

Files that arrive in a folder or bucket in Box become rows in Azure Cosmos DB as they land, so a database-driven process can pick them up without polling the storage system's API.

What you can sync between Azure Cosmos DB and Box

Representative objects on each side — any object or custom field can map to any target. Schemas are auto-detected; types are converted between the two systems.

Azure Cosmos DB objects Box objects How this pairing syncs
Partition keys Determine data distribution and must be included on writes for the sync to route items correctly. Users Managed and app users in the enterprise; provisioned, updated, and deprovisioned to keep Box access aligned with an HR or identity source. Partition keys is specific to Azure Cosmos DB and Users to Box — each maps to any object or custom field on the other side.
Change feed entries Ordered record of inserts and updates per partition, consumed for incremental sync. Groups Named user collections used for bulk collaboration; membership synced from a directory or IdP. Change feed entries is specific to Azure Cosmos DB and Groups to Box — each maps to any object or custom field on the other side.
Stored procedures and triggers Server-side logic scoped to a partition; relevant when writes must respect existing validation. Tasks Review or approval assignments on a file with due dates and states; read for workflow reporting or written to start approvals. Stored procedures and triggers is specific to Azure Cosmos DB and Tasks to Box — each maps to any object or custom field on the other side.
Databases Top-level namespaces that scope containers and throughput provisioning. Events Enterprise admin event stream, an audit log of uploads, deletes, logins, and shares across the account; read-only, consumed for reporting or change feeds. Databases is specific to Azure Cosmos DB and Events to Box — each maps to any object or custom field on the other side.
Containers The unit of partitioning and throughput; each container maps to a synced collection. Files Core content object with versions, name, size, and metadata; synced two-way so files and their attributes move between Box and a database or another store. Containers is specific to Azure Cosmos DB and Files to Box — each maps to any object or custom field on the other side.
Items (JSON documents) Schema-flexible JSON records read and written during sync; nested structures are flattened or mapped as needed. Folders Hierarchical containers whose tree, names, and parent moves are mirrored so a target system reflects Box's structure; the account root is always folder ID 0. Items (JSON documents) is specific to Azure Cosmos DB and Folders to Box — each maps to any object or custom field on the other side.

How changes propagate between Azure Cosmos DB and Box

Each direction of the sync is driven by what the source system can signal and what the destination accepts — detection, delivery, and expected latency below.

Azure Cosmos DB Box Sub-second propagation

DetectionChanges in Azure Cosmos DB are captured at the source via change data capture — no polling loop against its API. Built-in change feed exposing inserts and updates in order within each partition key range.

DeliveryEach detected change is written to Box through its API, with automatic retries and rate-limit backoff.

Box Azure Cosmos DB Sub-second propagation

DetectionBox notifies Stacksync of record changes through webhook events. V2 webhooks fire on triggers such as FILE.UPLOADED, FILE.TRASHED, and METADATA_INSTANCE.UPDATED.

DeliveryEach detected change is applied to Azure Cosmos DB as a row-level write, with types converted between the two schemas.

Rate-limit considerations

  • Box: Per user: 1,000 API calls per minute and 240 file uploads per minute; exceeding limits returns HTTP 429 with a Retry-After header. Box Business plans also carry a licensed monthly API-call allotment per enterprise.
