 For some applications, where the newest data is more valuable than historical data, data accumulation can be worse than data loss. In such cases, where you cannot afford to lose the most recently-produced data by rejecting produce requests after producers have filled the local disks during the period of paused uploads, there is a less safe pause and resume mechanism. This mechanism prioritizes the ability to receive new data over retaining data that cannot be uploaded when disks are full:
 
 - Set the xref:reference:properties/object-storage-properties.adoc#cloud_storage_enable_remote_allow_gaps[`cloud_storage_enable_remote_allow_gaps`] cluster configuration property to `true`. This allows for gaps in the logs of all Tiered Storage topics in the cluster.
-- Set the `redpanda.remote.allow_gaps` configuration property to `true`. This allows gaps for one specific topic. This topic-level configuration option overrides the cluster-level default. 
 
 When you pause uploads and set one of these properties to `true`, there may be gaps in the range of offsets stored in object storage. You can seamlessly resume uploads by setting `*allow_gaps` to `true` at either the cluster or topic level. If set to `false`, disk space could be depleted and produce requests would be throttled.
