Manage Batches of Items in a Push Source

Manage items in batches is the best way to ensure that you never get throttled by the service (see Push API Limits - Recommended Maximum Number of Items/Security Identities per Hour). A batch Push API operation allows you to forward many push operations to the service using only a few Push API calls, rather than performing hundreds (or thousands) of single Push API calls to achieve the same results.

Performing batch Push API operations is slightly more complex than performing single Push API operations, as doing so involves three distinct steps which are detailed in this article.

Step 1: Create a File Container

See Creating a File Container.

Step 2: Upload the Content Update into the File Container

Perform the following PUT request to upload the push operations required for your content update into the Amazon S3 file container you got from Step 1: Create a File Container.

PUT <MyUploadURI> HTTP/1.1
  
<HTTPHeaders>

{
  "addOrUpdate": [
    {
      <MyItemMetadata>*,
      "documentId": <MyItemToAddOrUpdateURI>,
      <"data"|"compressedBinaryData"|"compressedBinaryDataFileId">: <MyItemDataOrFileId>,
      "compressionType": <"UNCOMPRESSED"|"DEFLATE"|"GZIP"|"LZMA"|"ZLIB">,
      "fileExtension": <MyItemDataFileExtension>,
      "permissions": <MyItemPermissionModel>
    }*
  ],
  "delete": [
    {
      "documentId": <MyItemToDeleteURI>,
      "deleteChildren": <true|false>
    }*
  ]
}

Replace:

• <MyUploadUri> with the value of the uploadUri property you got in the response when you created your file container in Step 1: Create a File Container.

• <HTTPHeaders> with the keys-value pairs of the requiredHeaders object property you got in the response when you created your file container in Step 1: Create a File Container.

In the request body (see Item Models - BatchDocumentBody):

• For each item you include in the addOrUpdate array (see Item Models - DocumentBody):

  • Replace <MyItemMetadata>* with any number of arbitrary metadata key-values you want to include along with the item you’re adding or updating (see About Push Source Item Metadata).

  • Replace <MyItemToAddOrUpdateURI> with the URI of the item to add or update (e.g., http://www.example.com/toadd.html).

    Specifying a unique documentId value for each item is mandatory.

  • Replace <"data"|"compressedBinaryData"|"compressedBinaryDataFileId"> with the property you want to use to push the item data. You must also replace <MyItemDataOrFileId> accordingly (see Pushing Item Data).

  • If you’re using the compressedBinaryData or the compressedBinaryDataFileId property to push item data (see Using the compressedBinaryData Property and Using the compressedBinaryDataFileId Property):

    • Replace <"UNCOMPRESSED"|"DEFLATE"|"GZIP"|"LZMA"|"ZLIB"> with the actual compression algorithm that was applied to the item data.

      The compressionType value is case sensitive.

      Otherwise, you don’t need to include the compressionType property at all.

  • Replace <MyItemDataFileExtension> with the actual file extension which the Push API should use to interpret the item data (e.g., .txt, .html, etc.). This value must include a preceding dot (.) character.

    Although doing so is optional, you should generally specify a fileExtension.

  • If you want to establish a parent-child relationship between the item and other items in the same Push source:

    • Replace <MyItemParentId> with the @documentId of the parent item, or by the @documentId of the item your are adding or updating if this item itself is the parent (see About the parentId Property).

      Otherwise, you don’t need to include the parentId property at all in your request body.

  • If the target Push source is secured:

    • Replace <MyItemPermissionModel> by a valid permission model for the pushed item. See:

      • PermissionSetsModel / Simple Permission Model Definition Examples

      • PermissionLevelsModel / Complex Permission Model Definition Example

      Otherwise, you don’t need to include the permissions property at all.

• For each item you include in the delete array (see Item Models - DeletedItem):

  • Replace <MyItemToDeleteURI> with the URI of the item to delete (e.g., http://www.example.com/todelete.html).

  • Set the deleteChildren property to true if you want to recursively delete all items whose documentId is nested under the documentId to delete, or set it to false otherwise

    The deleteChildren property is set to false by default.

A successful response (200 OK) has no content, but indicates that the content update was successfully uploaded to the Amazon S3 file container.

          ]
        },
        // ...More permission sets...
      ]
    },

  ],
  "delete": [
    {
      "documentId": "http://www.example.com/todelete.html",
      "deleteChildren": true
    },
    // ...More items to delete...
  ]
}

{}

Step 3: Push the File Container into a Push Source

Use the Add, update, or delete a large number of encrypted items in a source operation to push the Amazon S3 file container into a Push source.

PUT https://api.cloud.coveo.com/push/v1/organizations/<MyOrganizationId>/sources/<MySourceId>/documents/batch?fileId=<MyFileId> HTTP/1.1
  
Content-Type: application/json
Authorization: Bearer <MyAccessToken>

{}

In the request path:

• Replace <MyOrganizationId> with the actual ID of the target Coveo organization (see Retrieve the Organization ID).

• Replace <MySourceId> with the actual ID of the target Push source (see Creating a Push Source).

In the query string:

• Replace <MyFileId> with the filedId you got from Step 1: Create a File Container.

In the Authorization HTTP header:

• Replace <MyAccessToken> with an access token that grants the Organization - View and Sources - View/Edit privileges in the target organization (see Creating an API key, Get the Privileges of an Access Token, and Get Your Coveo Platform Access Token).

A successful response (202 Accepted) has no content, but indicates that the operation was successfully forwarded to the service and that the batch of items is now enqueued to be processed by the Coveo Cloud indexing pipeline.
