Delete data

This page shows you how to use the delete endpoint to remove documents from a collection.

​

Delete documents by IDs

Since LambdaDB documents can always be efficiently accessed using their ID, deleting by ID is the most efficient way to remove specific records.

curl -i -X POST \
  --url https://{baseUrl}/projects/{projectName}/collections/{collectionName}/docs/delete \
  --header 'content-type: application/json' \
  --header 'x-api-key: <YOUR_API_KEY>' \
  --data '{
  "ids": [
    "<string>",
    "<string>",
    ...
  ]
}'

​

Delete documents by query

To delete documents based on their data, pass a filter query to the delete operation. This deletes all document matching the filter query.

For example, to delete all documents with genre “documentary” and year 2019 from a collection, use the following code:

curl -i -X POST \
  --url https://{baseUrl}/projects/{projectName}/collections/{collectionName}/docs/delete \
  --header 'content-type: application/json' \
  --header 'x-api-key: <YOUR_API_KEY>' \
  --data '{
  "filter": {
    "queryString": {
      "query": "genre:documentary AND year:2019"
    }
  }
}'

Delete an entire collection

To remove all documents from a collection, delete the collection and recreate it
