@Jeremyyang920 @ryanluu12345 @crash-overdrive A number of these release notes mention new metrics. As I mentioned previously, we should provide the metric names if a user is expected to be able to use them. If the metrics are internal, then I suggest not documenting them here. |

Outdated
| - Improved visibility into queue depth between each source frontend and the backend applier to the target. Updated logging to use lower log levels with clearer, less alarming wording. | ||
| - Improved throughput for tables in the replication stream that have no dependencies on one another. This increases parallelism and minimizes blocking of transactions that are mutually independent. | ||
| - The best effort window is now disabled by default to prevent unexpected mode switches that can lead to consistency issues and stalled replication due to failed target applies. | ||
| - Added checkpointing support for the Pebble stager in CockroachDB-to-X replication mode to better handle failures and ensure minimal data replay for consistency. |

@ryanluu12345 This shouldn't be in the release note since the pebble stager version isint public right?

Yes good point, let's remove anything referencing Pebble stager until we actually release it publically.

| - Added new metrics `target_apply_queue_utilization_percent` and `target_apply_queue_depth` to track target apply queue utilization, indicating when the queue should be resized. These metrics are only relevant to PostgreSQL, Oracle, and CockroachDB sources. | ||
| - Oracle sources now support configurable backpressure between the source and target applier. The new `target_apply_queue_depth` metric tracks queue depth. | ||
| - Improved visibility into queue depth between each source frontend and the backend applier to the target. Updated logging to use lower log levels with clearer, less alarming wording. | ||
