updateCollection

1. API Description

API feature: This API can update a collection.

API declaration: updateCollection(collectionName: string, options: array): Promise<Object>

This API can update collections, but currently supports updating indexes.

⚠️ Currently, this API can only update indexes, including creation and deletion.

• If an index already exists during creation, it will be deleted first and then recreated.
• Since a single API call can create multiple indexes simultaneously, partial failures may occur (while others succeed), and the API will throw an exception.

options	Required	Array<Option>	Configuration options

Option

Field	Required	Type	Description

Name	Required	String	Index name
Direction	Required	String	Index direction: 1 for ASC, -1 for DESC, 2d for bidirectional (must be placed first if present). Note: For geospatial indexes, set this value to "2dsphere".

DropIndex

Field	Required	Type	Description
IndexName	Required	String	Index name

Two independent methods for updating indexes: creating and deleting. CreateIndexes and DropIndexes cannot be passed simultaneously in options.

3. Return Results

Field	Required	Type	Description

import

1. API Description

API Feature: Import Data

API declaration: import(collectionName: string, file: object, options: object): Promise<Object>

Note:

• The API returns immediately, and the migration status (success|failure) can be queried via migrateStatus.
• Importing data requires first uploading the file to COS in the environment (same EnvId), so it will create objects in COS.
• Because the successful return of this function only indicates that the upload is successful, the import operation begins after uploading. This API cannot determine whether the import is complete. Therefore, the object needs to be manually deleted after use.

⁃ StopOnError	Optional	Boolean	whether to stop the import when encountering errors
⁃ ConflictMode	Optional	String	Conflict resolution method: insert or upsert

3. Return Results

Field	Required	Type	Description
