Connectors

Pecca has nine interfaces (eight connector families plus identity) with a few reference implementations each. The community adds the rest.

Interface	Purpose	Reference implementations
DataSource	read historical rows	csv, parquet, postgres, databricks, snowflake, bigquery, otel-traces, litellm, databricks-ai-gateway, mcp
Registry	models, versions, state, logs	local, mlflow, wandb
Notifier	events to chat	slack, teams, webhook, mcp
Ticketer	approvals	jira, github, manual, mcp
Scheduler	periodic jobs	cron, airflow, databricks_workflows
ServingTarget	deploy a version	onnx_local, docker_export, databricks_serving
Secrets	${VAR} values	env, vault, aws-secrets-manager
DocsPublisher	audit pages	markdown, confluence
Identity	who is approving	oidc (and local default)

A config block selects an implementation with type:. pecca plugins list shows everything registered. Optional dependencies are imported only when used (pip install 'pecca[databricks]', [snowflake], [bigquery], [mlflow], [wandb], [vault], [aws], [pdf], [all]). Connectors that talk to the network are tested with mocked HTTP; CI makes no network calls.
