AI Summary

This release adds OAUTHBEARER authentication support for Kafka connectors, introduces a new output_table_type parameter for MongoDB writes with snapshot and stream modes, enables automatic worker scaling based on pipeline load, and adds TLS configuration support for PostgreSQL writes.

Key Highlights

Kafka connectors now support OAUTHBEARER authentication
MongoDB write connector supports output_table_type with snapshot and stream_of_changes modes
Workers can automatically scale up/down based on pipeline load with configurable monitoring window
PostgreSQL write connector now supports TLS configuration via sslmode and sslrootcert
pw.xpacks.connectors.read now retries initial connection requests

New Features

OAUTHBEARER authentication for pw.io.kafka.read and pw.io.kafka.write
output_table_type parameter for pw.io.mongodb.write (stream_of_changes/snapshot modes)
Automatic worker scaling with worker_scaling_enabled and workload_tracking_window_ms
TLS configuration support for pw.io.postgres.write

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.
