| |
| <p>The interfaces can be implemented to make IOs available in other SDKs in addition to Beam SQL. |
| |
| <p><b>Internal only:</b> This interface is actively being worked on and it will likely change as |
| we provide implementations for more standard Beam IOs. We provide no backwards compatibility |
| guarantees and it should not be implemented outside of the Beam repository. |
