Adam Storm (ajstorm) commented:

In the docs on changefeeds, we mention the referenced cluster setting along with a link to the cluster settings page:

The kv.closed_timestamp.target_duration cluster setting can be used with changefeeds. Resolved timestamps will always be behind by at least the duration configured by this setting. However, decreasing the duration leads to more transaction restarts in your cluster, which can affect performance.

on that cluster settings page however, there is no mention of the referenced cluster setting. This is confusing because users don't know to what that cluster setting defaults, and its meaning.
