# Sinks Overview

> Connectors Filament can write to.

Filament ships five sink connectors today:

| Sink                                           | Package                    | Notes                                                           |
| ---------------------------------------------- | -------------------------- | --------------------------------------------------------------- |
| [PostgreSQL](/pages/connectors/sinks/postgres) | `connectors/postgres/sink` |                                                                 |
| [MySQL](/pages/connectors/sinks/mysql)         | `connectors/mysql/sink`    |                                                                 |
| [Iceberg](/pages/connectors/sinks/iceberg)     | `connectors/iceberg`       | Table-format sink with catalog support (generic, REST, Polaris) |
| [AWS S3](/pages/connectors/sinks/aws-s3)       | `connectors/object`        | S3-compatible endpoints (MinIO, etc.) via a custom `endpoint`   |
| [Stdout](/pages/connectors/sinks/stdout)       | `connectors/stdout`        | Prints records — useful for local development and debugging     |

Every sink implements the base `Sink` contract; some add optional
capabilities like staged/transactional writes, upserts, or typed DDL. See
[Optional interfaces](/pages/connectors/building-a-connector/optional-interfaces)
for the full list.
