MongoDB write connector supports snapshot mode for maintaining table state.
Workers can automatically scale up or down based on pipeline load.
Postgres write connector now supports TLS configuration.

New Features

Kafka OAUTHBEARER authentication support
MongoDB snapshot mode output_table_type
Automatic worker scaling with persistence
Postgres TLS configuration (sslmode, sslrootcert)
Connection retry logic for initial read requests

Full Release Notes

### Added
- `pw.io.kafka.read` and `pw.io.kafka.write` connectors now support OAUTHBEARER authentication.
- `pw.io.mongodb.write` connector now supports an `output_table_type` parameter with two modes: `stream_of_changes` (default) and `snapshot`. In `snapshot` mode, the connector maintains the current state of the Pathway table in MongoDB using the `_id` field as the primary key, while `stream_of_changes` preserves the existing behavior by writing all events with `time` and `diff` flags to reflect transactional minibatches and the nature of each change.
- Workers can now automatically scale up or down based on pipeline load, using a configurable monitoring window. This feature requires persistence to be enabled and can be configured via `worker_scaling_enabled` and `workload_tracking_window_ms` in `pw.persistence.Config`. Please refer to the tutorial for more details.
- `pw.io.postgres.write` now properly supports TLS configuration via `sslmode` and `sslrootcert` connection string parameters.

### Changed
- `pw.xpacks.connectors.read` now retries initial connection requests.
