-No description available.

+Configuration property: redpanda.cloud_topic.enabled


This will eventually be deleted on new runs. But this is auto-excluded from docs anyway

paulohtb6 · 2026-02-23T18:21:30Z

modules/reference/partials/properties/topic-properties.adoc

+Set the storage mode for this topic, controlling where Redpanda stores its data. This property supersedes the legacy <<redpandaremoteread,`redpanda.remote.read`>> and <<redpandaremotewrite,`redpanda.remote.write`>> properties.
+
+You can set this value at topic creation time or alter it later, although only certain transitions between modes are allowed.
+
+Accepted values:
+
+* `unset`: Defer to the legacy `redpanda.remote.read` and `redpanda.remote.write` topic properties for tiered storage configuration.
+* `local`: Store data only on local disks, with no object storage involvement.
+* `tiered`: Store data on local disks and replicate it to object storage using xref:manage:tiered-storage.adoc[Tiered Storage]. Equivalent to setting `redpanda.remote.read` and `redpanda.remote.write` to `true`.
+* `cloud`: Store data primarily in object storage using xref:manage:tiered-storage.adoc#cloud-topics[cloud topics].
+
+If not set explicitly, the topic inherits the cluster-level default from config_ref:default_redpanda_storage_mode,true,properties/cluster-properties[].


@WillemKauf agree with this description?

"if not set explicitly" means redpanda.storage.mode=unset, might want to reiterate that explicitly

paulohtb6 · 2026-02-23T18:22:05Z

modules/reference/partials/properties/cluster-properties.adoc

+Set the default storage mode for new topics. This value applies to any topic created without an explicit <<redpandastoragemode,`redpanda.storage.mode`>> setting.
+
+Accepted values:
+
+* `unset`: Defer to the legacy <<cloud_storage_enable_remote_read,`redpanda.remote.read`>> and <<cloud_storage_enable_remote_write,`redpanda.remote.write`>> topic properties for tiered storage configuration.
+* `local`: Store data only on local disks, with no object storage involvement.
+* `tiered`: Store data on local disks and replicate it to object storage using xref:manage:tiered-storage.adoc[Tiered Storage]. Equivalent to setting `redpanda.remote.read` and `redpanda.remote.write` to `true`.
+* `cloud`: Store data primarily in object storage using xref:manage:tiered-storage.adoc#cloud-topics[cloud topics].

So many of these indicate they were added in 25.3. I suspect most of the remaining ones are specific to 26.1. The tricky part here--given that no doc went out for Cloud Topics in 25.3, I think it might be confusing for users to see that and then find nothing in the 25.3 docs for Cloud Topics. I'll ask @mattschumpert about this today @paulohtb6.

Feediver1 · 2026-02-23T20:20:58Z

Also note that Cloud Topics requires an enterprise license, so should be "Cloud Topics".

docs-data/property-overrides.json

mattschumpert · 2026-02-23T22:52:25Z

We should consider all cloud topics properties as 'new' for 26.1 (even if added in 25.3) because for everybody except 1-2 private beta customers, they are new.

We could also throw the 25.3 ones into the cloud topics 25.3 private beta doc if its easy, but not the property refernece of course.
