Besides the upsert operation which has 6MB maximum payload size limit, LambdaDB also supports bulk upsert operation to insert or update multiple documents up to 200MB at once.

First, get the required information to upload payload to object storage:

LAMBDADB_PROJECT_API_KEY="YOUR_API_KEY"

curl -i -X GET \
  "https://{baseUrl}/projects/{projectName}/collections/{collectionName}/docs/bulk-upsert" \
  -H 'content-type: application/json' \
  -H 'x-api-key: $LAMBDADB_PROJECT_API_KEY'

The response will look like this:

{
  "url": "<string>",
  "type": "application/json",
  "httpMethod": "PUT",
  "objectKey": "<string>",
  "sizeLimitBytes": 209715200
}

Upload your documents as a one object using the provided URL and call bulk-upsert API with the corresponding objectKey you’ve just uploaded:

LAMBDADB_PROJECT_API_KEY="YOUR_API_KEY"

curl -i -X POST \
  "https://{baseUrl}/projects/{projectName}/collections/{collectionName}/docs/bulk-upsert" \
  -H 'content-type: application/json' \
  -H 'x-api-key: $LAMBDADB_PROJECT_API_KEY' \
  -d '{
    "objectKey": "<string>"
  }'
