Cognee Cloud can ingest data from external databases, SaaS applications, and file storage systems. Connectors are built on dlt (data load tool) and the Cognee Python SDK.
Databases Connect to relational databases using a connection string. Cognee extracts table data and processes it into the knowledge graph.
import cognee await cognee.serve() # Connect to Cognee Cloud # PostgreSQL await cognee.add( "postgresql://user:pass@host:5432/mydb" , dataset_name = "postgres_data" ) await cognee.cognify( datasets = [ "postgres_data" ])
Supported databases:
Database Connection string format PostgreSQL postgresql://user:pass@host:5432/dbMySQL mysql+pymysql://user:pass@host:3306/dbSQLite sqlite:///path/to/database.dbSQL Server mssql://user:pass@host:1433/db
SaaS applications Ingest data from SaaS tools using dlt source connectors. Install the relevant dlt extra and pass the source to cognee.add().
from dlt.sources.slack import slack_source source = slack_source( selected_channels = [ "general" , "engineering" ], start_date = datetime( 2025 , 1 , 1 ), ) await cognee.add(source, dataset_name = "slack_data" )
Extracts: channels, messages, users, threads.
pip install "dlt[notion]"
from dlt.sources.notion import notion_databases source = notion_databases() await cognee.add(source, dataset_name = "notion_data" )
Extracts: databases, pages, properties.
pip install "dlt[github]"
from dlt.sources.github import github_reactions source = github_reactions( "your-org" , "your-repo" ) await cognee.add(source, dataset_name = "github_data" )
Extracts: issues, pull requests, comments, reactions.
pip install "dlt[hubspot]"
from dlt.sources.hubspot import hubspot source = hubspot() await cognee.add(source, dataset_name = "hubspot_data" )
Extracts: contacts, companies, deals, tickets.
pip install "dlt[google_sheets]"
from dlt.sources.google_sheets import google_spreadsheet source = google_spreadsheet( spreadsheet_url = "https://docs.google.com/spreadsheets/d/..." , ) await cognee.add(source, dataset_name = "sheets_data" )
Extracts: rows and columns from specified sheets. For more connectors, see the dlt integration guide and the dlt source catalog .
File storage Upload files directly from cloud storage services using the Cognee SDK or the Data Ingestion API .
For S3 bucket integration, see S3 Storage .
All dlt sources work with both local Cognee and Cognee Cloud. When connected via cognee.serve(), data flows to your cloud tenant automatically.
