From 73f7e5055e4ad3583903a7f61508081d615473d5 Mon Sep 17 00:00:00 2001 From: micheleRP Date: Tue, 30 Jun 2026 21:08:13 -0600 Subject: [PATCH] DOC-14: document Cloud topic segment size default Add a Segment size row to the Cloud topic-properties table. Redpanda Cloud sets log_segment_size to 128 MiB at the cluster level, unlike self-managed Redpanda (1 GiB), and this was not documented anywhere in cloud-docs. The per-tier min/max are intentionally described as tier-dependent rather than hardcoded, pending Cloud-team confirmation.
