The content and layout look great! I think it's a really clean doc and intuitive. I left some comments just so Shashwat can clarify a few discrepancies I noted.
Regarding the layout, I don't think you need to show the "Staging" section for MySQL, Oracle, and PG sources. Staging is really only relevant for Cockroach sources. Can probably add conditional logic there. Other than that, sections look right to me.

lgtm pending suggestions
| - Interpretation: High values indicate target apply cannot keep up with incoming transactions. | ||
| - `target_apply_queue_utilization_percent` | ||
| - Description: Percentage of apply queue capacity utilization. | ||
| - Interpretation: Values above 90 percent indicate severe backpressure. Increase [`--targetApplyQueueSize`]({% link molt/replicator-flags.md %}#target-apply-queue-size) or investigate target database performance. |

Should this flag link be displayed for MySQL and Oracle, since "This flag applies only to CockroachDB and PostgreSQL (pglogical) sources"?

@crash-overdrive @ryanluu12345 Florence raised a really good point -- does the --targetApplyQueueSize only apply to CRDB and PG sources? If so, I need to clarify here.

it is applicable to Oracle
it is not applicable to MySQL.

Shashwat is right. Only CRDB, PG, and Oracle. MySQL upcoming.

Its only PG and Oracle. CRDB supports it too (with pebble stager) but we dont expose pebble stager publicly as of yet. So for now lets just mention PG and Oracle @taroface !

Good catch Shashwat! That's an oversight on my end, my mistake! Sorry @taroface

Just to confirm, we're talking about the --targetApplyQueueSize flag and not the target_apply_queue_size metric, right?

LGTM mod minor things!
Can we update the metric mutations_total to mutation_total and also add it to the Oracle section as oracle supports this metric as well!
Also can we move the Note for Checkpoint terminology to CRDB section only instead of all the sections? Also for some reason staging has the Note for Checkpoint terminology as well, dont know if thats intentional or not!
