Authorizations

​
Authorization
string
header
required

Bearer authentication header of the form Bearer <token>, where <token> is your auth token.

Path Parameters

​
collection_identifier
string
required

The ID or name of the collection to trigger

Body

application/json

Request to trigger (re)processing through a collection.

For bucket-sourced collections (tier 0): Discovers objects from source bucket(s) and creates a batch for processing. Use include_buckets to limit which source buckets to process from.

For collection-sourced collections (tier N): Processes existing documents from upstream collection(s). Use include_collections to limit which source collections to process from.

Use source_filters for field-level filtering on objects or documents.

Document Overwrite Behavior:

  • If source bucket has unique_key configured: Documents are UPSERTED (overwrites existing)
  • If source bucket has NO unique_key: New documents are CREATED (may cause duplicates)

To enable idempotent re-processing, configure unique_key on the source bucket.

​
include_buckets
string[] | null

Limit processing to objects from these specific buckets (IDs or names). Only applies to bucket-sourced collections. If not provided, all configured source buckets are used.

​
include_collections
string[] | null

Limit processing to documents from these specific collections (IDs or names). Only applies to collection-sourced collections. If not provided, all configured source collections are used.

​
object_ids
string[] | null

Limit processing to these specific object IDs. Only applies to bucket-sourced collections. This is a convenience shorthand — equivalent to using source_filters with {"AND": [{"field": "object_id", "operator": "in", "value": [...]}]}.

​
source_filters
LogicalOperator · object

Field-level filters for objects (bucket-sourced) or documents (collection-sourced). Uses LogicalOperator format (AND/OR/NOT). Use this to filter by metadata fields, status, or any other object/document properties.

Example:
{
  "AND": [
    {
      "field": "status",
      "operator": "eq",
      "value": "pending"
    }
  ]
}
​
dedup_strategy
enum<string> | null

How to handle sources already processed in prior batches. skip (default): skip sources already materialized in this collection. replace: delete existing documents for the re-processed sources and re-materialize them — this also clears the processed-objects resume ledger, so use it to recover a collection stuck with ledger entries but 0 materialized documents (the orphan/divergence state). force: process regardless, allowing duplicates.

Available options:
skip,
replace,
force

Response

Successful Response

Response after triggering collection processing.

Use batch_id or task_id to monitor progress via GET /v1/batches/{batch_id} or GET /v1/tasks/{task_id}.

​
batch_id
string
required

ID of the created batch for tracking progress.

​
task_id
string
required

Task ID for monitoring via GET /v1/tasks/{task_id}.

​
collection_id
string
required

ID of the collection being processed.

​
total_tiers
integer
required

Number of processing tiers in the DAG.

​
message
string
required

Human-readable status message.

​
source_bucket_ids
string[] | null

Bucket IDs that objects were discovered from (bucket-sourced collections).

​
source_collection_ids
string[] | null

Collection IDs that documents were read from (collection-sourced collections).

​
object_count
integer | null

Total number of objects included in the batch (bucket-sourced collections).

​
document_count
integer | null

Total number of documents to process (collection-sourced collections).
