Sources Overview

Filament ships eight source connectors today: two native database connectors, five manifest-driven SaaS connectors sharing one implementation, and a synthetic generator for testing.

Databases

Source	Package	Notes
PostgreSQL	`connectors/postgres/source`	Adaptive read-mode routing (keyset, bitmap, ctid); full + incremental + CDC
MySQL	`connectors/mysql/source`	Keyset reads plus GTID-based CDC

SaaS Apps

All five run on the same HTTP connector, configured by a declarative manifest rather than by their own Go package:

Source	Manifest	Notes
Attio	`attio.yaml`	23 resources — the deepest parent/child nesting of the five
GitHub	`github.yaml`	Repositories, issues, pull requests for one organization
Linear	`linear.yaml`	The one GraphQL manifest — everything else is REST
Notion	`notion.yaml`	Databases, pages, blocks
Slack	`slack.yaml`	The only bundled manifest with incremental sync

Custom & Testing

Source	Package	Notes
HTTP	`connectors/http`	The manifest-driven mechanism the five SaaS sources above run on; new APIs are onboarded declaratively
Sample	`connectors/sample`	Synthetic data, for testing pipelines without a real upstream

Every source implements the base Source contract; several add optional capabilities like resumability or CDC. See Optional interfaces for the full list.
