This page shows you how to manage your existing collections including listing, describing, and deleting operations.
List collections
Retrieve a complete list of all collections in your project along with their metadata and status information.
from lambdadb import LambdaDB
lambda_db = LambdaDB(
server_url="PROJECT_URL",
project_api_key="YOUR_API_KEY"
)
lambda_db.collections.list()
{
"collections": [
{
"projectName": "your-project",
"collectionName": "example-collection",
"indexConfigs": {
"title": {"type": "text"},
"category": {"type": "keyword"}
},
"numDocs": 1250,
"cloneSourceInfo": {
"sourceProjectId": "source-project-id",
"sourceIndexName": "source-collection",
"sourceIndexVersionId": "wR0NyDJbqDiHMaaV597GjczO2oGQyG7T"
},
"collectionStatus": "ACTIVE"
}
]
}
Describe a collection
Get detailed information about a specific collection, including its configuration, document count, and current status.
from lambdadb import LambdaDB
lambda_db = LambdaDB(
server_url="PROJECT_URL",
project_api_key="YOUR_API_KEY"
)
lambda_db.collections.get(collection_name="example-collection")
{
"projectName": "your-project",
"collectionName": "example-collection",
"indexConfigs": {
"title": {
"type": "text",
"analyzers": ["standard", "korean"]
},
"embedding": {
"type": "vector",
"dimensions": 768,
"similarity": "cosine"
}
},
"numDocs": 1250,
"cloneSourceInfo": {
"sourceProjectId": "source-project-id",
"sourceIndexName": "source-collection",
"sourceIndexVersionId": "wR0NyDJbqDiHMaaV597GjczO2oGQyG7T"
},
"collectionStatus": "ACTIVE"
}
Delete a collection
Permanently delete a collection and all of its associated data and resources. This operation cannot be undone.
from lambdadb import LambdaDB
lambda_db = LambdaDB(
server_url="PROJECT_URL",
project_api_key="YOUR_API_KEY"
)
lambda_db.collections.delete(collection_name="collection-to-delete")
Deleting a collection is irreversible and will permanently remove all documents and metadata. Make sure you have proper backups if needed before proceeding with this operation.
Collection status
Collections can have the following status values:
| Status | Description |
|---|
CREATING | Collection is being created and not yet available |
ACTIVE | Collection is ready for read/write operations |
DELETING | Collection is being deleted |
